Latitude and Longitude of U.S. and Canadian Cities, Major Cities: Latitude, Longitude, and Corresponding Time Zones. Columbus only obtained confirmation of his title on March 30, 1493, when the Catholic Monarchs, acknowledging the receipt of his letter, address Columbus for the first time as "our Admiral of the Ocean Sea and Vice-Roy and Governor of the islands which have been discovered in the Indies" ("nuestro Almirante del mar Ocano e Visorrey y Gobernador de las Islas que se han descubierto en las Indias"). [22] This eliminates chronometer error and watch error corrections. By 22 August 1972, after sending back data and a total of 60 pictures, Mars 2 and 3 concluded their missions. [6], In 1969, and as part of the Mars probe program, the Soviet Union prepared two identical 5-ton orbiters called M-69, dubbed by NASA as Mars 1969A and Mars 1969B. These rings have the capacity to transport the distinct biological, chemical, and physical properties of their originating waters to the new waters into which they travel. [citation needed]. Matthias Tomczak and J. Stuart Godfrey (2001). At the time, the pope was then deep in the midst of arbitrating between the claims of the crowns of Portugal and Spain over Columbus's discoveries. Clouds may prevent the detection of heat sources. As the king wrote Columbus (September 5, 1493), the Portuguese envoys had no clue where the islands were actually located ("no vienen informados de lo que es nuestro"[56]). Columbus's letter (particularly the Latin edition) forged the initial public perception of the newly discovered lands. Phobos 2, while successfully photographing Mars and Phobos, failed before it was set to release two landers to the surface of Phobos.[22]. Almost immediately after Columbus's arrival in Spain, printed versions of the letter began to appear. Modern smartphones act as personal GPS navigators for civilians who own them. [15] It also refers to an island called "Borinque" (Puerto Rico), unmentioned in the printed editions, that the natives report to lie between Hispaniola and Caribo. [13], Starting in 1960, the Soviets launched a series of probes to Mars including the first intended flybys and hard (impact) landing (Mars 1962B). [15] A fix is the intersection of two or more LOPs. [19] Some types of navigation are depicted in the table. The US$720 million spacecraft was built by Lockheed Martin under the supervision of the Jet Propulsion Laboratory, launched August 12, 2005, and entered Mars orbit on March 10, 2006. "Satellites Record Weakening North Atlantic Current Impact", "Climate crisis: Scientists spot warning signs of Gulf Stream collapse", "Gulf Stream could be veering toward irreversible collapse, a new analysis warns", "A crucial ocean circulation is showing signs of instability. [135] Starship is planned to have a payload of at least 100 tonnes. Roughly sixty percent of all spacecraft destined for Mars failed before completing their missions and some failed before their observations could begin. It is now increasingly believed that the Latin edition printed in Rome is actually a translation of the letter to Santangel, and that the letter to the Monarchs was never translated nor printed. Before actually navigating, the initial latitude and longitude and the INS's physical orientation relative to the earth (e.g., north and level) are established. For more U.S. locations including cities, towns, parks and more, use the Find Latitude and Longitude tool.See also Latitude and Longitude of World Cities. p.22. WebFor information on South Africa's response to COVID-19 please visit the COVID-19 Corona Virus South African Resource Portal. EUMETSAT Meteosat images are updated every 15 minutes. Located in Southeast Texas near Galveston Bay and the Gulf of Mexico, it is the seat and largest The letter reports the islands are located at 26N which falls just below the Canary latitude, so the letter worked almost in Portugal's favor, and forced the pope into the geographical contortions of confirming Spanish possession without violating prior treaties. The Mars Express Orbiter confirmed the presence of water ice and carbon dioxide ice at the planet's south pole, while NASA had previously confirmed their presence at the north pole of Mars. In particular, the printed editions omit practically all of Columbus's allusions to personal friction found in the manuscriptover the choice of ships, past treatment in the royal court, or the insubordination of the "one from Palos" (Martn Alonso Pinzn)as well as Columbus's bizarre call for crusade in the Holy Land. [22], Quartz crystal marine chronometers have replaced spring-driven chronometers aboard many ships because of their greater accuracy. Sydney, for example, has a longitude of about 151 east. [citation needed], Other future mission concepts include polar probes, Martian aircraft and a network of small meteorological stations. An INS is not affected by adverse weather conditions and it cannot be detected or jammed. A perfect solution to accommodate low windows, large wall art, or low-profile mattresses, the Lottie upholstered platform bed frame with a short headboard is a streamlined version of our bestselling upholstered foundation. Columbus also gives an account of some of his own activities in the letters. [4] A summary of Ponce de Len's voyage log on April 22, 1513, noted, "A current such that, although they had great wind, they could not proceed forwards, but backwards and it seems that they were proceeding well; at the end, it was known that the current was more powerful than the wind. Unlike older rovers that relied on solar power, Perseverance is nuclear powered, to survive longer than its predecessors in this harsh, dusty environment. The stationary lander InSight is investigating the deep interior of Mars. However, a third version of the letter, contained in a 16th-century manuscript collection known as the Libro Copiador, was discovered in 1985. However, attempts to contact the lander failed. RDF antennas are easy to spot on German World War II aircraft, as loops under the rear section of the fuselage, whereas most US aircraft enclosed the antenna in a small teardrop-shaped fairing. "Genaro H. de Volafan" (F.A. [6], On 10 March 2006, NASA's Mars Reconnaissance Orbiter (MRO) probe arrived in orbit to conduct a two-year science survey. [54] (There is some confusion whether Eximiae devotionis preceded or followed the second Inter caetera; it is commonly supposed that the first Inter caetera ("May 3") was drafted in April and received in Spain on May 17, the second Inter caetera ("May 4") drafted in June, and received in Spain by July 19 (a copy was forwarded to Columbus in early August);[55] while Eximiae diviones ("May 3") is normally assumed written sometime in July. WebThe Gulf Stream, together with its northern extension the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States then veers east near 36 latitude (North Carolina) and moves toward Northwest Europe as the North Atlantic Current. 2750'), the boundary set by the 1479 Treaty of Alcovas as the area of Portuguese exclusivity (confirmed by the papal bull Aeterni regis of 1481).[51]. Bush. [44] Such storms have the potential to create strong winds and extensive damage to the United States' Southeast Coastal Areas. Jane (1930: pp. In aviation, pilots undertake air navigation training as part of learning to fly. The second mirror, referred to as the "horizon glass", is fixed to the front of the frame. With options available on weekdays and weekends, plus online, instructor-led and blended learning course formats, you can get the CPR training you need on your schedule. The MRO captured the first image of a series of active avalanches near the planet's north pole in 2008. Decca, OMEGA, and LORAN-C are three similar hyperbolic navigation systems. WebLongitude (/ l n d tj u d /, AU and UK also / l -/) is a geographic coordinate that specifies the eastwest position of a point on the surface of the Earth, or another celestial body. [22], The basic element for time generation is a quartz crystal oscillator. This is a probable reference to the Caribs from the Leeward Islands, although neither the word "cannibal" nor "Carib" appears in the printed editions (however, in the Copiador letter, he claims the "monsters" come from an island called "Caribo", possibly Dominica). [22] Times and frequencies of radio time signals are listed in publications such as Radio Navigational Aids.[22]. [33] Its robotic arm dug into the Martian soil and the presence of water ice was confirmed on June 20, 2008. Jane (1930: pp. He made detailed maps of Newfoundland prior to making three voyages to the Pacific, during At least one afternoon sun line, in case the stars are not visible at twilight. 2. (It is also unlikely Columbus initiated the long letter in the middle of the stormhe surely had more urgent matters to attend to; he probably wrote the main body of the letter in the calm period before the storm began on February 12, and hurried to finish them when the storm hit.)[23]. He reports that La Navidad is located near reported gold mines, and is a well-placed entrepot for the commerce that will doubtlessly soon be opened with the Great Khan ("gran Can") on the mainland. The Mars 1M programs (sometimes dubbed Marsnik in Western media) was the first Soviet unmanned spacecraft interplanetary exploration program, which consisted of two flyby probes launched towards Mars in October 1960, Mars 1960A and Mars 1960B (also known as Korabl 4 and Korabl 5 respectively). Although scholars have tentatively embraced the Libro Copiador as probably authentic, it is still in the early stages of careful and critical scrutiny, and should be treated a bit cautiously. A river of sea water, called the Atlantic North Equatorial Current, flows westwards off the coast of Central Africa. [46], The USSR intended to have the first artificial satellite of Mars beating the planned American Mariner 8 and Mariner 9 Mars orbiters. Mars is a rocky planet, like Earth, that formed around the same time, yet with only half the diameter of Earth, and a far thinner atmosphere; it has a cold and desert-like surface. de Varhagen), editor, 1858, De Lollis (1894: pp. a path derived from a defined initial bearing. Initially, the system was to be used for navigating nuclear bombers across the North Pole to Russia. [21] But should the ECDIS fail, the navigator will have to rely on his skill in the manual and time-tested procedures. National Imagery and Mapping Agency, 2001:182. The Latin editions contain no postscript, but end with a verse epigram added by Leonardus de Cobraria, Bishop of Monte Peloso. The printed Spanish letter is dated aboard the caravel "on the Canary Islands" on February 15, 1493. On his third attempt, in another bull also called Inter caetera, written in the summer and backdated to May 4, 1493, the Pope once again confirmed the Spanish claim on the Indies more explicitly with a longitude line of demarcation granting all lands 100 leagues west of Cape Verde (not merely those discovered by "her envoys") as the exclusive dominion of the Crown of Castile (with no explicit safeguards for prior Portuguese treaties or grants). Our editors update and regularly refine this enormous body of information to bring you reliable information. The eastward route across the Pacific, also known as the tornaviaje (return trip) was only discovered forty years later, when Spanish cosmographer Andrs de Urdaneta sailed from the Philippines, north to parallel 39, and hit the eastward Kuroshio Current which took its galleon across the Pacific. [19] The navigator becomes a system manager, choosing system presets, interpreting system output, and monitoring vessel response.[19]. Navigation on ships is usually always conducted on the bridge. The Pope chimed in with yet another bull on the matter, Dudum siquidum, written in December but officially backdated September 26, 1493, where he went further than before, and gave Spain claim over any and all lands discovered by her envoys sailing west, in whatever hemisphere those lands happened to be. A navigator shoots a number of stars in succession to give a series of overlapping lines of position. Convinced nonetheless he had discovered the edges of Asia, Columbus set sail back to Spain on January 15, 1493, aboard the caravel Nia. The Mars 2020 mission by NASA was launched on 30 July 2020 on a United Launch Alliance Atlas V rocket from Cape Canaveral. In full, the opening of the first Roman edition reads:[76], The corrections (Ferdinand & Isabella, Gabriel Sanchez, Leander de Cosco) were undertaken in the Second and Third Roman editions later that same year, possibly as a result of complaints by Castilian emissaries in Rome who felt their Queen (and spellings) were given short-shrift by the Aragonese. De Lollis (1894); Jane (1930); more recently, see Ramos (1983, 1986). The possibility of a Gulf Stream collapse has been covered by many news publications. Climatic Wind Data for the United States. 2, The identification of Santangel is due to Navarrete (1825: vol. Similar to latitude, the longitude of a place on Earth is the angular distance east or west of the prime meridian or Greenwich meridian. WebOpportunity Zones are economically distressed communities, defined by individual census tract, nominated by Americas governors, and certified by the U.S. Secretary of the Treasury via his delegation of that authority to the Internal Revenue Service. Columbus ends the letter urging their Majesties, the Church, and the people of Spain to give thanks to God for allowing him to find so many souls, hitherto lost, ready for conversion to Christianity and eternal salvation. The moon and sun may also be used. This is India's first mission to Mars, and with it, ISRO became the fourth space agency to successfully reach Mars after the Soviet Union, NASA (USA) and ESA (Europe). Live weather images are updated every 10 minutes from NOAA GOES and JMA Himawari geostationary satellites. It was common for royal and commercial agents to accost and interview returning sailors in the docks, so the Portuguese king would likely have the information he sought soon enough. [100] The first letter in the copybook purports to be a copy of the original letter sent by Christopher Columbus to the Catholic Monarchs from Lisbon announcing the discovery. The pope assigned the Crown of Castile "all lands discovered by their envoys" (i.e. [49] This is reinforced by the discovery of the Libro Copiador. (Note: in the Copiador version, Columbus makes no mention of the latitudes nor the native name Guanahanin.).

Because of the "Almirante" signature and other clues, it is believed that all the Spanish editions are probably indirect, that is, that they were probably not directly copied from Columbus's original manuscript letter, but are themselves copies of earlier unknown copies or editions. Ife, Barry W. (1992) "Introduction to the Letters from America", King's College London. That is, upon taking an initial bearing, one proceeds along the same bearing, without changing the direction as measured relative to true or magnetic north. The lists do not show all contributions to every state ballot measure, or each independent expenditure committee Overuse of these devices, whether in the vehicle or on foot, can lead to a relative inability to learn about navigated environments, resulting in sub-optimal navigation abilities when and if these devices become unavailable. Earlier in the letter, Columbus had spoken also of the land of "Avan" ("Faba" in the Copiador letter), in the western parts of Juana, where men are said to be "born with tails" ("donde nacan la gente con cola")probably a reference to the Guanajatabey of western Cuba. As noted before, these were being intensively negotiated in the papal court throughout 149394. Read customer reviews and common Questions and Answers for Latitude Run Part #: W004138417 on this page. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east.. At 165,250,000 square kilometers (63,800,000 square In retrospect, however, some hints are given earlier. [124] Proposals for human exploration of Mars have been made throughout the history of space exploration; currently there are multiple active plans and programs to put humans on Mars within the next ten to thirty years, both governmental and private, some of which are listed below. In addition to bearings, navigators also often measure distances to objects. Already by June 1493, the letter had been translated by a poet into Italian verse, and that version went through multiple editions in the next couple of years. The sextant consists of two primary assemblies. [13] For example, a minimum occurred in the 1969 and 1971 launch windows, rising to a peak in the late 1970s, and hitting another low in 1986 and 1988. The practice of taking celestial observations from the deck of a rolling ship, often through cloud cover and with a hazy horizon, is by far the most challenging part of celestial navigation. Labels and map data OpenStreetMap contributors. According to Columbus, when persuaded to interact, the natives are quite generous and nave, willing to exchange significant amounts of valuable gold and cotton for useless glass trinkets, broken crockery, and even shoelace tips ("cabos de agugetas"). Ice navigation, the region the ship will be passing through and the hydrographic information on the route. [16] In the Copiador letter, Columbus suggests that he is bringing normal (full-haired) Indians back to Spain who have been to Jamaica, who will report more about it (rather than bringing the island's own bald-headed inhabitants, as claimed in the printed letters). Morning sun observation. Another possibility that has been explored for deep space navigation is Pulsar navigation, which compares the X-ray bursts from a collection of known pulsars in order to determine the position of a spacecraft. WebNorth America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. The cost of maintaining the system is approximately US$750 million per year,[32] including the replacement of aging satellites, and research and development. Winsor, J. The librarians fished the pieces out of the wastepaper basket and put it back together; it is currently held as a curiosity by the New York Public Library. [13] In addition, the lowest available transfer energy varies on a roughly 16-year cycle. Mars Global Surveyor completed its primary mission on January 31, 2001, and completed several extended mission phases until communication was lost in 2007. Each second of error is equivalent to 15 seconds of longitude error, which at the equator is a position error of .25 of a nautical mile, about the accuracy limit of manual celestial navigation. WebPersonal Collection Statement. The mission was part of NASA's Mars Exploration Program, which includes three previous successful landers: the two Viking program landers in 1976; and Mars Pathfinder probe in 1997. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. It would be highly presumptuous for Columbus to sign his name that way in February or March, when the original letter was drafted, before that success was confirmed by the royal court. [18] The amount of data returned by probes increased dramatically as technology improved. [citation needed]. [25] These two processes produce water that is denser and colder (or more precisely, water that is still liquid at a lower temperature). In his letter, Columbus seems to attempt to present the islands of the Indies as suitable for future colonization. As a result, historians tend to agree that the Barcelona edition (which has no date or publisher name, and the appearance of being hurriedly printed) was probably the first to be published, and was the closest to the original manuscript. The Fobos-Grunt mission suffered a complete control and communications failure shortly after launch and was left stranded in low Earth orbit, later falling back to Earth. We've got you covered with our map collection. Satellites have limited accuracy. The Brazilian historian Francisco Adolfo de Varnhagen found another hand-written copy of the Spanish letter to Santangel among the papers of the Colegio Mayor de Cuenca in Salamanca. MAVEN was launched 18 November 2013 and reached Mars on 22 September 2014. [37], The Mars Science Laboratory mission was launched on November 26, 2011 and it delivered the Curiosity rover on the surface of Mars on August 6, 2012 UTC. Indeed, there was no point in reprinting the Latin editions either, once the Treaty of Tordesillas was signed in June 1494. Even before Herrera arrived John II had sent his own emissary, Ruy de Sande, to the Spanish court, reminding the Spanish monarchs that their sailors were not allowed to sail below Canaries latitude, and suggesting all expeditions to the west be suspended. [39] The prologue notes that the translation into Latin was undertaken by the notary Leander de Cosco and completed on April 29, 1493 ("third of the calends of May"). The plan operates through three distinct phases leading up to fully sustained colonization. veinte instead of xxxiii), but most of the spellings are in proper Castilian, although it is uncertain how much of this was in the original, and how much was massaged by Gonzalez or Navarrete in their transcriptions. The Trinidad sailed east from the Philippines, trying to find a maritime path back to the Americas, but was unsuccessful. [62][63] In addition to scientific objectives, the Mars Pathfinder mission was also a "proof-of-concept" for various technologies, such as an airbag landing system and automated obstacle avoidance, both later exploited by the Mars Exploration Rovers. The "Mars Curse": Why Have So Many Missions Failed? [15] This wind pattern applies a stress to the subtropical ocean surface with negative curl across the north Atlantic Ocean. Rated 4.7 out of 5 stars.7636 total votes. Columbus says the monsters are reported to be long-haired, very ferocious, and "eat human flesh" ("los quales comen carne humana"). NASA is still aiming for human missions to Mars in the 2030s, though Earth independence could take decades longer. [42] While the Gulf Stream is expected to slow down as the Atlantic Meridional Overturning Circulation (AMOC) weakens, it will not collapse even if the AMOC were to collapse. [1] In this sense, navigation includes orienteering and pedestrian navigation.[1]. While all the Spanish editions are very close to each other, historians believe they are not merely corrected reprints of each other, but that all derive independently (or at least in consultation with) an unknown prior edition or manuscript. Hurricane Sandy in 2012 was a recent example of a hurricane passing over the Gulf Stream and gaining strength. The car-size rover weighs about 1 ton, with a robotic arm that reaches about 7 feet (2.1m), zoom cameras, a chemical analyzer and a rock drill. S. Businger, T. M. Graziano, M. L. Kaplan, and R. A. Rozumalski. [46] Subtropical cyclones also tend to be generated near the Gulf Stream. [44][45], In the US, Bowditch's American Practical Navigator is a free available encyclopedia of navigation issued by the US Government. [34][35] The mission concluded on November 10, 2008 after contact was lost. Early Pacific Polynesians used the motion of stars, weather, the position of certain wildlife species, or the size of waves to find the path from one island to another. Towards the end of the letter, Columbus reveals that local Indians told him about the possible existence of cannibals, which he refers to as "monsters" ("monstruos"). The table below gives the latitude and longitude of dozens of U.S. and Canadian cities. He speaks of a local king near Navidad whom he befriended and treated him as a brother ("y grand amistad con el Rey de aquella tierra en tanto grado que se preciava de me lhamar e tener por hermano")almost certainly a reference to Guacanagarx, cacique of Marin.[17]. The primary scientific objectives of the lander mission were to search for biosignatures and observe meteorologic, seismic and magnetic properties of Mars. Due to radio's ability to travel very long distances "over the horizon", it makes a particularly good navigation system for ships and aircraft that might be flying at a distance from land. A ESA-NASA team produced a three-launch architecture concept for a Mars sample return, which uses a rover to cache small samples, a Mars ascent stage to send it into orbit, and an orbiter to rendezvous with it above Mars and take it to Earth. In 1488 Bartolomeu Dias reached the Indian Ocean by this route. 3940); Anzovin (2000: p. 109). The height of Polaris in degrees above the horizon is the latitude of the observer, within a degree or so. Columbus), so long as they are not possessed by any Christian owner (which Columbus's letter confirmed). [22] Given the strength and proximity of the Gulf Stream, beaches along the East Coast of the United States may be more vulnerable to large sea-level anomalies, which significantly impact rates of coastal erosion. [31][32] As Santangel had a lot riding on the results of this expedition, perhaps more than anybody else, it was perhaps natural for Columbus to address his first letter to him. [13] The island of women reportedly abounds in copper, which the warrior-women forge into weapons and shields. National Imagery and Mapping Agency, 2001:164. Columbus exaggerates the size of these lands, claiming Juana is greater in size than Great Britain ("maior que Inglaterra y Escocia juntas") and Hispaniola larger than the Iberian peninsula ("en cierco tiene mas que la Espana toda"). [45], Strong extratropical cyclones have been shown to deepen significantly along a shallow frontal zone, forced by the Gulf Stream, during the cold season. Noontime determination the day's run and day's set and drift. [11] He also names (5) La Isla Juana (Joanam in Latin, modern Cuba) and (6) the island of La Spaola (Hispana in the Latin letter, modern Hispaniola). Coverage is limited, and glitches/anomalies are common. As is well known, instead of reaching Asia, Columbus stumbled upon the Caribbean islands of the Americas. By knowing which point on the rotating earth a celestial object is above and measuring its height above the observer's horizon, the navigator can determine his distance from that subpoint. It consisted of a lander and a small 10.6-kilogram (23lb) wheeled robotic rover named Sojourner, which was the first rover to operate on the surface of Mars. All necessary tools, parts, and instructions are ingeniously packed in the back of the headboard for smooth sailing. A transcription and English translation can be found in Zamora (1993).[99]. WebFranklin's lost expedition was a failed British voyage of Arctic exploration led by Captain Sir John Franklin that departed England in 1845 aboard two ships, HMS Erebus and HMS Terror, and was assigned to traverse the last unnavigated sections of the Northwest Passage in the Canadian Arctic and to record magnetic data to help determine whether a better "A Letter addressed to the noble Lord Raphael Sanchez, &tc. So Columbus realized the Spanish court needed to be informed of the results of his voyage as soon as possible. [70] Gonzalez's copy has since been lost, and exists now only in the Navarrete transcription. The mission's scientific objective was to search for and characterize a wide range of rocks and soils that hold clues to past water activity on Mars. [32], Phoenix landed on the north polar region of Mars on May 25, 2008. WebAbout Our Coalition. This spacecraft was designed as an orbiter only, while the next two probes of project M-71, Mars 2 and Mars 3, were multipurpose combinations of an orbiter and a lander with small skis-walking rovers that would be the first planet rovers outside the Moon. [36] The warming effect provided by the Gulf Stream has allowed fairly large settlements to be developed and maintained on the coast of Northern Norway, including Troms, the third largest city north of the Arctic Circle. For the corrected second Roman edition, see Quaritch (1893: The epigram by R.L. [19] Mars 6 failed during descent but did return some corrupted atmospheric data in 1974. A Latin translation of the letter (addressed to Gabriel Sanchez) was printed in Rome about a month later. Four are in the modern Bahamas: (1) Sant Salvador (for which he also gives the local name, Guanaham in the Spanish edition and Guanahanin in the Latin letter; modern English texts normally render it as Guanahani), (2) Santa Maria de Concepcion, (3) Ferrandina (Fernandinam in the Latin version, in modern texts Fernandina), and (4) la isla Bella (given as Hysabellam in the Latin version, and La Isabela in modern texts). Most other early Latin editions are reprints of that edition. A letter written by Christopher Columbus on February 15, 1493 is the first known document announcing the results of his first voyage that set out in 1492 and reached the Americas. Mars has a reputation as a difficult space exploration target; just 25 of 55 missions through 2019, or 45.5%, have been fully successful, with a further three partially successful and partially failures. [3], As of May2021[update], there are three operational rovers on the surface of Mars, the Curiosity and Perseverance rovers, both operated by the United States of America space agency NASA, as well as the Zhurong rover, part of the Tianwen-1 mission by the China National Space Administration (CNSA).
