Returning to the basic concept of current flows in a conductor, consider what happens if a half-wave dipole is not connected to a feed point, but instead shorted out. Electrically this forms a single 1⁄2-wavelength element. But the overall current pattern is the same; the current will be zero at the two ends, and reach a maximum in the center. Thus signals near the design frequency will continue to create a standing wave pattern. Any varying electrical current, like the standing wave in the element, will radiate a signal. In this case, aside from resistive losses in the element, the rebroadcast signal will be significantly similar to the original signal in both magnitude and shape. If this element is placed so its signal reaches the main dipole in-phase, it will reinforce the original signal, and increase the current in the dipole. Elements used in this way are known as passive elements.

Question: Element used to provide support to the original signal are called?
Answer: passive elements.

The convention in the English language is to call nearly all national heads of government "prime minister" (sometimes modified to the equivalent term of premier), regardless of the correct title of the head of government as applied in his or her respective country. The few exceptions to the rule are Germany and Austria, whose heads of government titles are almost always translated as Chancellor; Monaco, whose head of government is referred to as the Minister of State; and Vatican City, for which the head of government is titled the Secretary of State. In the case of Ireland, the head of government is occasionally referred to as the Taoiseach by English speakers. A stand-out case is the President of Iran, who is not actually a head of state, but the head of the government of Iran. He is referred to as "president" in both the Persian and English languages.

As with bacterial classification, identification of bacteria is increasingly using molecular methods. Diagnostics using DNA-based tools, such as polymerase chain reaction, are increasingly popular due to their specificity and speed, compared to culture-based methods. These methods also allow the detection and identification of "viable but nonculturable" cells that are metabolically active but non-dividing. However, even using these improved methods, the total number of bacterial species is not known and cannot even be estimated with any certainty. Following present classification, there are a little less than 9,300 known species of prokaryotes, which includes bacteria and archaea; but attempts to estimate the true number of bacterial diversity have ranged from 107 to 109 total species – and even these diverse estimates may be off by many orders of magnitude.

Question: What tool does DNA based diagnostics use?
Answer: polymerase chain reaction.

Colossus was the world's first electronic digital programmable computer. It used a large number of valves (vacuum tubes). It had paper-tape input and was capable of being configured to perform a variety of boolean logical operations on its data, but it was not Turing-complete. Nine Mk II Colossi were built (The Mk I was converted to a Mk II making ten machines in total). Colossus Mark I contained 1500 thermionic valves (tubes), but Mark II with 2400 valves, was both 5 times faster and simpler to operate than Mark 1, greatly speeding the decoding process.

South Slavic historically formed a dialect continuum, i.e. each dialect has some similarities with the neighboring one, and differences grow with distance. However, migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans have caused large-scale population displacement that broke the dialect continuum into many geographical pockets. Migrations in the 20th century, primarily caused by urbanization and wars, also contributed to the reduction of dialectal differences.

---

Question: What caused the dialect continuum to become fractured?
Answer: migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans.

All Protestant denominations reject the notion of papal supremacy over the Church universal and generally deny the Roman Catholic doctrine of transubstantiation, but they disagree among themselves regarding the real presence of Christ in the Eucharist. The various denominations generally emphasize the priesthood of all believers, the doctrine of justification by faith alone (sola fide) rather than by or with good works, and a belief in the Bible alone (rather than with Catholic tradition) as the highest authority in matters of faith and morals (sola scriptura). The "Five solae" summarize the reformers' basic differences in theological beliefs in opposition to the teaching of the Roman Catholic Church of the day.

The United States joined World War II in December 1941 after the Japanese attack on Pearl Harbor. On the European front, U.S. Army troops formed a significant portion of the forces that captured North Africa and Sicily, and later fought in Italy. On D-Day, June 6, 1944, and in the subsequent liberation of Europe and defeat of Nazi Germany, millions of U.S. Army troops played a central role. In the Pacific War, U.S. Army soldiers participated alongside the United States Marine Corps in capturing the Pacific Islands from Japanese control. Following the Axis surrenders in May (Germany) and August (Japan) of 1945, army troops were deployed to Japan and Germany to occupy the two defeated nations. Two years after World War II, the Army Air Forces separated from the army to become the United States Air Force in September 1947 after decades of attempting to separate. Also, in 1948, the army was desegregated by order of President Harry S. Truman.

Contrary to how the Protestant Reformers were often characterized, the concept of a catholic or universal Church was not brushed aside during the Protestant Reformation. On the contrary, the visible unity of the catholic or universal church was seen by the Protestant reformers as an important and essential doctrine of the Reformation. The Magisterial reformers, such as Martin Luther, John Calvin, and Huldrych Zwingli, believed that they were reforming the Roman Catholic Church, which they viewed as having become corrupted. Each of them took very seriously the charges of schism and innovation, denying these charges and maintaining that it was the Roman Catholic Church that had left them. In order to justify their departure from the Roman Catholic Church, Protestants often posited a new argument, saying that there was no real visible Church with divine authority, only a spiritual, invisible, and hidden church—this notion began in the early days of the Protestant Reformation.

Question: Instead of a visible church, what did Protestants believe there was?
Answer: a spiritual, invisible, and hidden church.

On December 12, the Supreme Soviet of the Russian SFSR formally ratified the Belavezha Accords and renounced the 1922 Union Treaty. The Russian deputies were also recalled from the Supreme Soviet of the USSR. The legality of this action was questionable, since Soviet law did not allow a republic to unilaterally recall its deputies. However, no one in either Russia or the Kremlin objected. Any objections from the latter would have likely had no effect, since the Soviet government had effectively been rendered impotent long before December. In effect, the largest and most powerful republic had seceded from the Union. Later that day, Gorbachev hinted for the first time that he was considering stepping down.

Sexual identity and sexual behavior are closely related to sexual orientation, but they are distinguished, with sexual identity referring to an individual's conception of themselves, behavior referring to actual sexual acts performed by the individual, and orientation referring to "fantasies, attachments and longings." Individuals may or may not express their sexual orientation in their behaviors. People who have a homosexual sexual orientation that does not align with their sexual identity are sometimes referred to as 'closeted'. The term may, however, reflect a certain cultural context and particular stage of transition in societies which are gradually dealing with integrating sexual minorities. In studies related to sexual orientation, when dealing with the degree to which a person's sexual attractions, behaviors and identity match, scientists usually use the terms concordance or discordance. Thus, a woman who is attracted to other women, but calls herself heterosexual and only has sexual relations with men, can be said to experience discordance between her sexual orientation (homosexual or lesbian) and her sexual identity and behaviors (heterosexual).

Britain also sent troops to protect British business enterprise, harbour rights, and consulate office. This was followed by an eight-year civil war, during which each of the three powers supplied arms, training and in some cases combat troops to the warring Samoan parties. The Samoan crisis came to a critical juncture in March 1889 when all three colonial contenders sent warships into Apia harbour, and a larger-scale war seemed imminent. A massive storm on 15 March 1889 damaged or destroyed the warships, ending the military conflict.

An airbase, sometimes referred to as an air station or airfield, provides basing and support of military aircraft. Some airbases, known as military airports, provide facilities similar to their civilian counterparts. For example, RAF Brize Norton in the UK has a terminal which caters to passengers for the Royal Air Force's scheduled TriStar flights to the Falkland Islands. Some airbases are co-located with civilian airports, sharing the same ATC facilities, runways, taxiways and emergency services, but with separate terminals, parking areas and hangars. Bardufoss Airport , Bardufoss Air Station in Norway and Pune Airport in India are examples of this.

LEDs have been developed by Seoul Semiconductor that can operate on AC power without the need for a DC converter. For each half-cycle, part of the LED emits light and part is dark, and this is reversed during the next half-cycle. The efficacy of this type of HP-LED is typically 40 lm/W. A large number of LED elements in series may be able to operate directly from line voltage. In 2009, Seoul Semiconductor released a high DC voltage LED, named as 'Acrich MJT', capable of being driven from AC power with a simple controlling circuit. The low-power dissipation of these LEDs affords them more flexibility than the original AC LED design.

Some of the second-generation renewables, such as wind power, have high potential and have already realised relatively low production costs. Global wind power installations increased by 35,800 MW in 2010, bringing total installed capacity up to 194,400 MW, a 22.5% increase on the 158,700 MW installed at the end of 2009. The increase for 2010 represents investments totalling €47.3 billion (US$65 billion) and for the first time more than half of all new wind power was added outside of the traditional markets of Europe and North America, mainly driven, by the continuing boom in China which accounted for nearly half of all of the installations at 16,500 MW. China now has 42,300 MW of wind power installed. Wind power accounts for approximately 19% of electricity generated in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland. In Australian state of South Australia wind power, championed by Premier Mike Rann (2002–2011), now comprises 26% of the state's electricity generation, edging out coal fired power. At the end of 2011 South Australia, with 7.2% of Australia's population, had 54%of the nation's installed wind power capacity. Wind power's share of worldwide electricity usage at the end of 2014 was 3.1%. These are some of the largest wind farms in the world:

In Arthurian legend, Avalon became associated with Glastonbury Tor when monks at Glastonbury Abbey claimed to have discovered the bones of King Arthur and his queen. What is more certain is that Glastonbury was an important religious centre by 700 and claims to be "the oldest above-ground Christian church in the World" situated "in the mystical land of Avalon." The claim is based on dating the founding of the community of monks at AD 63, the year of the legendary visit of Joseph of Arimathea, who was supposed to have brought the Holy Grail. During the Middle Ages there were also important religious sites at Woodspring Priory and Muchelney Abbey. The present Diocese of Bath and Wells covers Somerset – with the exception of the Parish of Abbots Leigh with Leigh Woods in North Somerset – and a small area of Dorset. The Episcopal seat of the Bishop of Bath and Wells is now in the Cathedral Church of Saint Andrew in the city of Wells, having previously been at Bath Abbey. Before the English Reformation, it was a Roman Catholic diocese; the county now falls within the Roman Catholic Diocese of Clifton. The Benedictine monastery Saint Gregory's Abbey, commonly known as Downside Abbey, is at Stratton-on-the-Fosse, and the ruins of the former Cistercian Cleeve Abbey are near the village of Washford.

By 1979, with the establishment of the Foundation for Ancient Research and Mormon Studies (FARMS) as a California non-profit research institution, an effort led by Robert F. Smith began to take full account of Larson’s work and to publish a Critical Text of the Book of Mormon. Thus was born the FARMS Critical Text Project which published the first volume of the 3-volume Book of Mormon Critical Text in 1984. The third volume of that first edition was published in 1987, but was already being superseded by a second, revised edition of the entire work, greatly aided through the advice and assistance of then Yale doctoral candidate Grant Hardy, Dr. Gordon C. Thomasson, Professor John W. Welch (the head of FARMS), Professor Royal Skousen, and others too numerous to mention here. However, these were merely preliminary steps to a far more exacting and all-encompassing project.

Rejecting offers to direct Jaws 2, King Kong and Superman, Spielberg and actor Richard Dreyfuss re-convened to work on a film about UFOs, which became Close Encounters of the Third Kind (1977). One of the rare films both written and directed by Spielberg, Close Encounters was a critical and box office hit, giving Spielberg his first Best Director nomination from the Academy as well as earning six other Academy Awards nominations. It won Oscars in two categories (Cinematography, Vilmos Zsigmond, and a Special Achievement Award for Sound Effects Editing, Frank E. Warner). This second blockbuster helped to secure Spielberg's rise. His next film, 1941, a big-budgeted World War II farce, was not nearly as successful and though it grossed over $92.4 million worldwide (and did make a small profit for co-producing studios Columbia and Universal) it was seen as a disappointment, mainly with the critics.

With the initial investment of £4,200, the new trial force of the Thames River Police began with about 50 men charged with policing 33,000 workers in the river trades, of whom Colquhoun claimed 11,000 were known criminals and "on the game." The force was a success after its first year, and his men had "established their worth by saving £122,000 worth of cargo and by the rescuing of several lives." Word of this success spread quickly, and the government passed the Marine Police Bill on 28 July 1800, transforming it from a private to public police agency; now the oldest police force in the world. Colquhoun published a book on the experiment, The Commerce and Policing of the River Thames. It found receptive audiences far outside London, and inspired similar forces in other cities, notably, New York City, Dublin, and Sydney.
