29-538: It is one of the heaviest-used locks in Germany, with a daily average of 107 commercial vessels passing through in 2003 and 30 million shipping tonnes per year. The chambers of the double lock have usable areas of 24 x 270 m. The lock is open for passage 24/7/365 and shuttles ships up or down with a water exchange rate of 165 m³/s per chamber, achieving a rise or fall of 1.5 m per minute. The lock retains at least 3.5 m water depth during normal low-water conditions. In 1840

58-506: A long arm is not the same as an extended arm ). Synonyms are also a source of euphemisms . Metonymy can sometimes be a form of synonymy: the White House is used as a synonym of the administration in referring to the U.S. executive branch under a specific president. Thus, a metonym is a type of synonym, and the word metonym is a hyponym of the word synonym . The analysis of synonymy, polysemy , hyponymy, and hypernymy

87-519: A German-French treaty was concluded for the construction of the Gambsheim and Iffezheim barrages. The construction of the barrage Iffezheim started in 1974. In 1977 the power station, lock and weir were put into operation. A contract to build the fish passes at Iffezheim and Gambsheim was signed in 1997. The fish pass in Iffezheim was put into operation in 2000, the one in Gambsheim in 2006. In 2009

116-586: A form of onoma ( ὄνομα 'name'). Synonyms are often from the different strata making up a language. For example, in English, Norman French superstratum words and Old English substratum words continue to coexist. Thus, today there exist synonyms like the Norman-derived people , liberty and archer , and the Saxon-derived folk , freedom and bowman . For more examples, see

145-748: A temporary basis, in order to clean and sanitize their establishments. After the widespread availability of vaccines, however, many such businesses have not returned to 24-hour service for a variety of reasons. Some proprietors in the United States originally blamed pandemic unemployment benefits for a lack of workers, yet employers still struggled to resume pre-pandemic hours after these programs were sunsetted, citing continued staff shortages and demands for better working conditions among jobseekers. Many businesses that were once broadly open for 24/7 operations only resumed such service across some of their establishments or have ended 24/7 operations altogether, as in

174-470: A torrent, consists of 37 individual basins in a row with a water depth of 1.5 m and a total length of 300 m. The Iffezheim fish pass was inaugurated in 2000, Gambsheim was opened in 2006. The construction of the fish pass in Iffezheim was financed by the two states France and Germany and the RKI GmbH. In connection with the fish pass, machine 6 was put into operation as a so-called lock current turbine. This

203-891: A way: 24-7-365. 24/7 service might be offered by a supermarket , convenience store , ATM , automated online assistant , filling station , restaurant , concierge services or a staffed datacenter , or a staffing company that specializes in providing nurses since often nurses cover shifts 24/7 at hospital which are open 24/7. 24/7 services may also include taxicabs , security services , and in densely populated urban areas, construction crews . Public 24/7 services often include those provided by emergency medical providers , police , fire and emergency telephone numbers , such as 9-1-1 in North America. Transport services like airports , airlines , and ferry services, and in some cases trains and buses, may provide 24-hour service. Examples of public transport services operating 24/7 include

232-624: Is coinages , which may be motivated by linguistic purism . Thus, the English word foreword was coined to replace the Romance preface . In Turkish, okul was coined to replace the Arabic-derived mektep and mederese , but those words continue to be used in some contexts. Synonyms often express a nuance of meaning or are used in different registers of speech or writing. Various technical domains may employ synonyms to convey precise technical nuances. Some writers avoid repeating

261-612: Is service that is available at any time and usually, every day. An alternate orthography for the numerical part includes 24×7 (usually pronounced "twenty-four by seven"). The numerals stand for "24 hours a day, 7 days a week". Less commonly used, 24/7/52 (adding "52 weeks") and 24/7/365 service (adding "365 days") make it clear that service is available every day of the year. Synonyms include around-the-clock service (with/without hyphens) and all day every day , especially in British English , and nonstop service , but

290-571: Is a word , morpheme , or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language , the words begin , start , commence , and initiate are all synonyms of one another: they are synonymous .

They are in operation 24 hours a day in three shifts and are maintained and serviced by the waterways and shipping office Freiburg. Every year, between 25,700 (2008) and 40,600 (1990) ships with approx. 24.4 (2009) to 30.9 (2000) million tonnes of goods pass through

377-421: Is inherent to taxonomy and ontology in the information science senses of those terms. It has applications in pedagogy and machine learning , because they rely on word-sense disambiguation . The word is borrowed from Latin synōnymum , in turn borrowed from Ancient Greek synōnymon ( συνώνυμον ), composed of sýn ( σύν 'together, similar, alike') and - ōnym - ( -ωνυμ- ),

406-668: The Grand Duchy of Baden and France concluded an agreement on Rhine regulation after Johann Gottfried Tulla . In 1902, the Alsatian engineer Koechlin made a push to use the water power of the Rhine. In 1928 the expansion of the Rhine began with the Grand Canal d'Alsace and the first four power stations (Kembs to Vogelgrün), four further barrages in the so-called loop solution (Marckolsheim to Strasbourg) followed in 1959. In 1969

435-1477: The New York City Subway , Staten Island Railway , PATH , PATCO , the Copenhagen Metro , and the Red Line and Blue Line of the Chicago "L" . Industrial and manufacturing facilities—especially those that operate near or at capacity, or which depend upon processes (such as production lines ) that are costly to suspend—often provide 24/7 services. Similarly, utilities generally must provide multiple 24/7 services. For instance, an electricity provider will handle outage reports 24/7 and dispatch emergency repair technicians 24/7, in addition to monitoring electrical infrastructure and producing electricity at all times. The same applies to telecommunications and internet service providers. Many crisis centers and crisis hotlines provide 24/7 services. Many 24/7 services operate continuously at all times with complete shift staff. 24/7 services that can utilize virtual offices , such as call centers , may employ daytime agents in alternating time zones . In some cases, 24/7 services may be temporarily unavailable under certain circumstances. Such scenarios may include scheduled maintenance , upgrades or renovation , emergency repair , and injunction . 24/7 services which depend upon

464-580: The Sunday trading laws prevent many stores from truly opening 24/7, but they sometimes advertise as such. Some core services such as filling stations are exempt from the law requiring them to close.

Synonym A synonym

493-404: The context long time or extended time are synonymous, but long cannot be used in the phrase extended family . Synonyms with exactly the same meaning share a seme or denotational sememe , whereas those with inexactly similar meanings share a broader denotational or connotational sememe and thus overlap within a semantic field . The former are sometimes called cognitive synonyms and

522-730: The list of Germanic and Latinate equivalents in English . Loanwords are another rich source of synonyms, often from the language of the dominant culture of a region. Thus, most European languages have borrowed from Latin and ancient Greek, especially for technical terms, but the native terms continue to be used in non-technical contexts. In East Asia , borrowings from Chinese in Japanese , Korean , and Vietnamese often double native terms. In Islamic cultures, Arabic and Persian are large sources of synonymous borrowings. For example, in Turkish , kara and siyah both mean 'black',

551-505: The Germanic term only as a noun, but has Latin and Greek adjectives: hand , manual (L), chiral (Gk); heat , thermal (L), caloric (Gk). Sometimes the Germanic term has become rare, or restricted to special meanings: tide , time / temporal , chronic . Many bound morphemes in English are borrowed from Latin and Greek and are synonyms for native words or morphemes: fish , pisci- (L), ichthy- (Gk). Another source of synonyms

580-470: The case of Walmart . 24/7 workplaces can put employees under conditions that limit their personal life choices and development. Calls for a rehumanisation of the 24/7 workplace have therefore been voiced. Some have also remarked on the "collective mania" especially in the US that takes a sort of pride in the "work at all times" attitude exemplified by the 24/7 concept. In England, Wales, and Northern Ireland,

609-461: The construction of the 5th turbine in Iffezheim started. At the end of 2011, the water law permit for the installation of a 5th turbine in the Rhine power plant Gambsheim was granted. This will increase the power plant capacity to 1420 m³/s. The additional turbine was pun into operation by 18 October 2013. f> The weir of the barrage in Iffezheim is situated on the French side of the Rhine, so that

638-497: The event of disruption, and minimum standards of overall reliability. Critical infrastructure may be supported by failover systems, electric generators , and satellite communications. In the event of catastrophic disaster, some 24/7 services prepare entirely redundant, parallel infrastructures, often in other geographic regions. At the beginning of the COVID-19 pandemic in 2020, many stores ended 24/7 operations, ostensibly on

667-631: The former being a native Turkish word, and the latter being a borrowing from Persian. In Ottoman Turkish , there were often three synonyms: water can be su (Turkish), âb (Persian), or mâ (Arabic): "such a triad of synonyms exists in Ottoman for every meaning, without exception". As always with synonyms, there are nuances and shades of meaning or usage. In English, similarly, there often exist Latin (L) and Greek (Gk) terms synonymous with Germanic ones: thought , notion (L), idea (Gk); ring , circle (L), cycle (Gk). English often uses

696-444: The latter can also refer to other things, such as public transport services which go between two stations without stopping. The Oxford English Dictionary (OED) defines the term as "twenty-four hours a day, seven days a week; constantly". It lists its first reference to 24/7 to be from a 1983 story in the US magazine Sports Illustrated in which Louisiana State University player Jerry Reynolds describes his jump shot in just such

725-502: The latter, near-synonyms, plesionyms or poecilonyms. Some lexicographers claim that no synonyms have exactly the same meaning (in all contexts or social levels of language) because etymology , orthography , phonic qualities, connotations , ambiguous meanings, usage , and so on make them unique. Different words that are similar in meaning usually differ for a reason: feline is more formal than cat ; long and extended are only synonyms in one usage and not in others (for example,

754-542: The locks in freight and cargo traffic. In 1987 the International Commission for the Protection of the Rhine (ICPR) has drawn up a programme of measures aimed, inter alia, at the reintroduction of salmon into the Rhine. One of the projects to this end was the construction of the fish passes at Iffezheim and Gambsheim, which was approved in the contract of 4 March 1997. The canal, which is modelled on

783-406: The physical presence of employees at a given location may also be interrupted when a minimum number of employees cannot be present due to scenarios such as extreme weather , death threats , natural disasters , or mandatory evacuation . Some 24/7 services close during major holidays . 24/7 services often employ complex schemes that ensure their resistance to potential disruption, resilience in

812-422: The same word in close proximity, and prefer to use synonyms: this is called elegant variation . Many modern style guides criticize this. Synonyms can be any part of speech , as long as both words belong to the same part of speech. Examples: Synonyms are defined with respect to certain senses of words: pupil as the aperture in the iris of the eye is not synonymous with student . Similarly, he expired means

841-580: The whole barrage is approximately mirror-inverted to the next higher situated barrage Gambsheim. It consists of six weir fields, each 20 m wide. One weir field consists of a hydraulically operated flap and a chain-driven pressure segment. The weir ensures the flow of the Rhine in the event of water flows that are greater than the capacity of the power plant. The entire plant is designed for a maximum water flow of 7500 m³/s. The double sluice consists of two sluice chambers, each 270 metres long and 24 metres wide. The difference in height between headwater and tailwater
