102-452: The name of the city is derived from early Egyptian Zawty ( Z3JW.TJ ) (late Egyptian, Səyáwt ) adopted into the Coptic as Syowt ⲥⲓⲟⲟⲩⲧ [sɪˈjowt] , which means " Guardian " of the northern approach of Upper Egypt . In Graeco-Roman Egypt , it was called Lycopolis or Lykopolis ( Greek : Λυκόπολις , " ἡ Λύκων πόλις "), ('wolf city') Lycon , or Lyco . Ancient Asyut

204-773: A literary language , and was also the language of the New Kingdom administration. Texts written wholly in Late Egyptian date to the Twentieth Dynasty of Egypt and later. Late Egyptian is represented by a large body of religious and secular literature , comprising such examples as the Story of Wenamun , the love poems of the Chester–Beatty I papyrus, and the Instruction of Any . Instructions became

306-576: A synthetic language , Egyptian by the Late Egyptian phase had become an analytic language . The relationship between Middle Egyptian and Late Egyptian has been described as being similar to that between Latin and Italian. The Late Egyptian stage is taken to have ended around the 8th century BC, giving rise to Demotic. Demotic is a later development of the Egyptian language written in the Demotic script , following Late Egyptian and preceding Coptic ,

408-425: A depth of about 3 to 6 feet (0.91 to 1.83 m). To protect pipes from impact , abrasion , and corrosion , a variety of methods are used. These can include wood lagging (wood slats), concrete coating, rockshield, high-density polyethylene , imported sand padding, sacrificial cathodes and padding machines. Crude oil contains varying amounts of paraffin wax and in colder climates wax buildup may occur within

510-589: A distinction is made between a "flowline" and a pipeline. The former is an intrafield pipeline, in the sense that it is used to connect subsea wellheads , manifolds and the platform within a particular development field. The latter, sometimes referred to as an "export pipeline", is used to bring the resource to shore. The construction and maintenance of marine pipelines imply logistical challenges that are different from those onland, mainly because of wave and current dynamics, along with other geohazards . In Nigeria oil pipelines get bored by thieves, in 2022, during

612-558: A few have survived that were written in hieratic and (later) demotic. There was also a form of cursive hieroglyphs , used for religious documents on papyrus, such as the Book of the Dead of the Twentieth Dynasty ; it was simpler to write than the hieroglyphs in stone inscriptions, but it was not as cursive as hieratic and lacked the wide use of ligatures . Additionally, there was a variety of stone-cut hieratic, known as "lapidary hieratic". In

714-495: A few specialists in the language. For all other purposes, the Egyptological pronunciation is used, but it often bears little resemblance to what is known of how Egyptian was pronounced. The following consonants are reconstructed for Archaic (before 2600 BC) and Old Egyptian (2686–2181 BC), with IPA equivalents in square brackets if they differ from the usual transcription scheme: / l / has no independent representation in

816-471: A fuel in oil fields to heat various facilities used by the oil drillers or equipment and trucks used in the oil patch. EG: Propane will convert from a gas to a liquid under light pressure, 100 psi, give or take depending on temperature, and is pumped into cars and trucks at less than 125 psi (860 kPa) at retail stations. Pipelines and rail cars use about double that pressure to pump at 250 psi (1,700 kPa). The distance to ship propane to markets

918-422: A local aristocratic family. It remained in possession of the family until 1995 when it was sold to the state. There are plans to restore the mansion and turn it into a museum. 27°11′N 31°10′E  /  27.183°N 31.167°E  / 27.183; 31.167 Egyptian language The Egyptian language , or Ancient Egyptian ( r n kmt ; "speech of Egypt") is an extinct branch of

1020-462: A nominal feminine suffix * -at , a nominal prefix m- , an adjectival suffix -ī and characteristic personal verbal affixes. Of the other Afroasiatic branches, linguists have variously suggested that the Egyptian language shares its greatest affinities with Berber and Semitic languages, particularly Arabic (which is spoken in Egypt today) and Hebrew . However, other scholars have argued that

1122-542: A pipeline is currently being constructed from North Dakota to Illinois, commonly known as the Dakota Access Pipeline . As more North American pipelines are built, even more exports of LNG, propane, butane, and other natural gas products occur on all three US coasts. To give insight, North Dakota Bakken region's oil production has grown by 600% from 2007 to 2015. North Dakota oil companies are shipping huge amounts of oil by tanker rail car as they can direct

1224-452: A pipeline system are: Since oil and gas pipelines are an important asset of the economic development of almost any country, it has been required either by government regulations or internal policies to ensure the safety of the assets, and the population and environment where these pipelines run. Pipeline companies face government regulation, environmental constraints and social situations. Government regulations may define minimum staff to run

1326-723: A pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage , slurry , water , beer , hot water or steam for shorter distances and even pneumatic systems which allow for the generation of suction pressure for useful work and in transporting solid objects. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills , or where canals or channels are poor choices due to considerations of evaporation , pollution , or environmental impact. Oil pipelines are made from steel or plastic tubes which are usually buried. The oil

1428-501: A pipeline. Often these pipelines are inspected and cleaned using pigging , the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. The devices are also known as "scrapers" or "Go-devils". "Smart pigs" (also known as "intelligent" or "intelligence" pigs) are used to detect anomalies in the pipe such as dents, metal loss caused by corrosion, cracking or other mechanical damage. These devices are launched from pig-launcher stations and travel through

1530-442: A popular literary genre of the New Kingdom, which took the form of advice on proper behavior. Late Egyptian was also the language of New Kingdom administration. Late Egyptian is not completely distinct from Middle Egyptian, as many "classicisms" appear in historical and literary documents of this phase. However, the difference between Middle and Late Egyptian is greater than the difference between Middle and Old Egyptian. Originally

1632-500: A presently rated 250,000 barrels equivalent per day pipeline, it will be expanded to between 1.0 and 1.3 million barrels per day. It will bring western oil to refineries in Ontario, Michigan, Ohio, Pennsylvania, Quebec and New York by early 2014. New Brunswick will also refine some of this western Canadian crude and export some crude and refined oil to Europe from its deep water oil ULCC loading port. Although pipelines can be built under

1734-449: A problem for pipeline companies. In this case, the detection levels should be under two percent of maximum flow, with a high expectation for location accuracy. Various technologies and strategies have been implemented for monitoring pipelines, from physically walking the lines to satellite surveillance. The most common technology to protect pipelines from occasional leaks is Computational Pipeline Monitoring or CPM. CPM takes information from

1836-444: A scribe jokes that his colleague's writing is incoherent like "the speech of a Delta man with a man of Elephantine ." Recently, some evidence of internal dialects has been found in pairs of similar words in Egyptian that, based on similarities with later dialects of Coptic, may be derived from northern and southern dialects of Egyptian. Written Coptic has five major dialects, which differ mainly in graphic conventions, most notably

1938-462: A set of screens or Human Machine Interface , showing the operational conditions of the pipeline. The operator can monitor the hydraulic conditions of the line, as well as send operational commands (open/close valves, turn on/off compressors or pumps, change setpoints, etc.) through the SCADA system to the field. To optimize and secure the operation of these assets, some pipeline companies are using what

2040-503: A stressed vowel (⟨ bjn ⟩ = */ˈbaːjin/ 'bad') and as ⟨ jj ⟩ word-medially immediately before a stressed vowel ( ⟨ḫꜥjjk⟩ = */χaʕˈjak/ 'you will appear') and are unmarked word-finally (⟨ jt ⟩ = /ˈjaːtVj/ 'father'). In Middle Egyptian (2055–1650 BC), a number of consonantal shifts take place. By the beginning of the Middle Kingdom period, / z / and / s / had merged, and

2142-510: A stressed vowel in syllables that had been closed in earlier Egyptian (compare ⲛⲟⲩⲃ < */ˈnaːbaw/ 'gold' and ⲧⲁⲡ < * /dib/ 'horn'). The phonemes /d g z/ occur only in Greek loanwords, with rare exceptions triggered by a nearby /n/ : ⲁⲛⲍⲏⲃⲉ/ⲁⲛⲥⲏⲃⲉ < ꜥ.t n.t sbꜣ.w 'school'. Earlier *d ḏ g q are preserved as ejective t' c' k' k ' before vowels in Coptic. Although

2244-644: A transliteration of the corresponding Demotic "alphabetical" sign(s) in angle brackets ⟨ ⟩ . More changes occur in the 1st millennium BC and the first centuries AD, leading to Coptic (1st or 3rd – c. 19th centuries AD). In Sahidic ẖ ḫ ḥ had merged into ϣ š (most often from ḫ ) and ϩ / h / (most often ẖ ḥ ). Bohairic and Akhmimic are more conservative and have a velar fricative / x / ( ϧ in Bohairic, ⳉ in Akhmimic). Pharyngeal *ꜥ had merged into glottal / ʔ / after it had affected

2346-465: A uniliteral hieroglyph. Egyptian scholar Gamal Mokhtar noted that the inventory of hieroglyphic symbols derived from "fauna and flora used in the signs [which] are essentially African", reflecting the local wildlife of North Africa, the Levant and southern Mediterranean. In "regards to writing, we have seen that a purely Nilotic, hence [North] African origin not only is not excluded, but probably reflects

2448-649: Is a 525-kilometre (326 mi) slurry pipeline which is planned to transport iron ore from the Minas-Rio mine (producing 26.5 million tonnes per year) to the Port of Açu in Brazil. An existing example is the 85-kilometre (53 mi) Savage River Slurry pipeline in Tasmania , Australia, possibly the world's first when it was built in 1967. It includes a 366-metre (1,201 ft) bridge span at 167 metres (548 ft) above

2550-644: Is a TransCanada natural gas line going north across the Niagara region bridges. This gas line carries Marcellus shale gas from Pennsylvania and other tied in methane or natural gas sources into the Canadian province of Ontario. It began operations in the fall of 2012, supplying 16 percent of all the natural gas used in Ontario. This new US-supplied natural gas displaces the natural gas formerly shipped to Ontario from western Canada in Alberta and Manitoba, thus dropping

2652-432: Is a system of pipes for long-distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than 2,175,000 miles (3,500,000 km) of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. The main attribute to pollution from pipelines

2754-556: Is also a lowering in elevation in mid Egypt , from the Mediterranean and the Red Sea . This gives the city and nearby towns and villages the similar properties of a continental climate , meaning that the city has harsh and chilly cold winter weather, and very hot but non-humid summers . During summer the temperature can exceed 42 °C (108 °F). Yet, in winter Asyut gets below 0 °C (32 °F) temperatures during

2856-598: Is also the longest-attested human language, with a written record spanning over 4,000 years. Its classical form, known as " Middle Egyptian ," served as the vernacular of the Middle Kingdom of Egypt and remained the literary language of Egypt until the Roman period . By the time of classical antiquity , the spoken language had evolved into Demotic , and by the Roman era , diversified into various Coptic dialects . These were eventually supplanted by Arabic after

2958-467: Is called "Advanced Pipeline Applications", which are software tools installed on top of the SCADA system, that provide extended functionality to perform leak detection, leak location, batch tracking (liquid lines), pig tracking, composition tracking, predictive modeling, look ahead modeling, and operator training. Pipeline networks are composed of several pieces of equipment that operate together to move products from location to location. The main elements of

3060-468: Is caused by corrosion and leakage. Pipeline and Gas Journal' s worldwide survey figures indicate that 118,623 miles (190,905 km) of pipelines are planned and under construction. Of these, 88,976 miles (143,193 km) represent projects in the planning and design phase; 29,647 miles (47,712 km) reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through

3162-474: Is dated from the oldest known complete sentence, including a finite verb , which has been found. Discovered in the tomb of Seth-Peribsen (dated c.  2690 BC ), the seal impression reads: Extensive texts appear from about 2600 BC. An early example is the Diary of Merer . The Pyramid Texts are the largest body of literature written in this phase of the language. One of its distinguishing characteristics

Asyut - Misplaced Pages Continue

3264-732: Is home to a large textile industry. The city also produces fine pottery, inlaid woodwork, and rugs. Asyut is the terminus of the Ras Shukheir-Asyut oil pipeline , the terminus of the Cairo -Asyut gas pipeline and the beginning of the proposed Asyut- Qena gas pipeline, the last two being part of the Nile Valley Gas Company Pipeline Project. Aysut is next to the Aysut Dam across the Nile river in

3366-503: Is less efficient to produce and transport due to greater heat losses. Heat transfer oils are generally not used for economic and ecological reasons. The typical annual loss of thermal energy through distribution is around 10%, as seen in Norway's district heating network. District heating pipelines are normally installed underground, with some exceptions. Within the system, heat storage may be installed to even out peak load demands. Heat

3468-445: Is moved through the pipelines by pump stations along the pipeline. Natural gas (and similar gaseous fuels) are pressurized into liquids known as natural gas liquids (NGLs). Natural gas pipelines are constructed of carbon steel . Hydrogen pipeline transport is the transportation of hydrogen through a pipe. Pipelines are one of the safest ways of transporting materials as compared to road or rail, and hence in war, pipelines are often

3570-625: Is much shorter, as thousands of natural-gas processing plants are located in or near oil fields. Many Bakken Basin oil companies in North Dakota, Montana, Manitoba and Saskatchewan gas fields separate the NGLs in the field, allowing the drillers to sell propane directly to small wholesalers, eliminating the large refinery control of product and prices for propane or butane. The most recent major pipeline to start operating in North America

3672-452: Is not a contrastive feature; all obstruents are voiceless and all sonorants are voiced. Stops may be either aspirated or tenuis (unaspirated), although there is evidence that aspirates merged with their tenuis counterparts in certain environments. The following table presents the consonants of Demotic Egyptian. The reconstructed value of a phoneme is given in IPA transcription, followed by

3774-686: Is odorless unless mixed with a mercaptan odorant where required by a regulating authority. A major ammonia pipeline is the Ukrainian Transammiak line connecting the TogliattiAzot facility in Russia to the exporting Black Sea -port of Odesa . Pipelines have been used for transportation of ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States. The main problems related to

3876-431: Is over 2,800 kilometres (1,700 mi) long, and is connected to wells tapping an aquifer over 500 metres (1,600 ft) underground. District heating or teleheating systems consist of a network of insulated feed and return pipes which transport heated water, pressurized hot water , or sometimes steam to the customer. While steam is hottest and may be used in industrial processes due to its higher temperature, it

3978-399: Is sometimes reserved for the earliest use of hieroglyphs, from the late fourth through the early third millennia BC. At the earliest stage, around 3300 BC, hieroglyphs were not a fully developed writing system , being at a transitional stage of proto-writing ; over the time leading up to the 27th century BC, grammatical features such as nisba formation can be seen to occur. Old Egyptian

4080-609: Is still in operation. As of 2004 , there are 900 miles (1,400 km) of low pressure hydrogen pipelines in the US and 930 miles (1,500 km) in Europe. Two millennia ago, the ancient Romans made use of large aqueducts to transport water from higher elevations by building the aqueducts in graduated segments that allowed gravity to push the water along until it reached its destination. Hundreds of these were built throughout Europe and elsewhere, and along with flour mills were considered

4182-424: Is the best-documented variety of the language, and has attracted the most attention by far from Egyptology . While most Middle Egyptian is seen written on monuments by hieroglyphs, it was also written using a cursive variant , and the related hieratic . Middle Egyptian first became available to modern scholarship with the decipherment of hieroglyphs in the early 19th century. The first grammar of Middle Egyptian

4284-405: Is the most desirable option, but ethanol's affinity for water and solvent properties require the use of a dedicated pipeline, or significant cleanup of existing pipelines. Slurry pipelines are sometimes used to transport coal or ore from mines. The material to be transported is closely mixed with water before being introduced to the pipeline; at the far end, the material must be dried. One example

4386-406: Is the tripling of ideograms , phonograms, and determinatives to indicate the plural. Overall, it does not differ significantly from Middle Egyptian, the classical stage of the language, though it is based on a different dialect. In the period of the 3rd dynasty ( c.  2650  – c.  2575 BC ), many of the principles of hieroglyphic writing were regularized. From that time on, until

4488-609: Is transferred into the central heating of the dwellings through heat exchangers at heat substations , without mixing of the fluids in either system. Bars in the Veltins-Arena , a major football ground in Gelsenkirchen , Germany, are interconnected by a 5-kilometre (3.1 mi) long beer pipeline. In Randers city in Denmark, the so-called Thor Beer pipeline was operated. Originally, copper pipes ran directly from

4590-528: Is usually known as the "Main Control Room". In this center, all the data related to field measurement is consolidated in one central database. The data is received from multiple RTUs along the pipeline. It is common to find RTUs installed at every station along the pipeline. The SCADA system at the Main Control Room receives all the field data and presents it to the pipeline operator through

4692-461: The Afro-Asiatic languages that was spoken in ancient Egypt . It is known today from a large corpus of surviving texts, which were made accessible to the modern world following the decipherment of the ancient Egyptian scripts in the early 19th century. Egyptian is one of the earliest known written languages , first recorded in the hieroglyphic script in the late 4th millennium BC . It

4794-513: The Coptic Catholic Church . Most hieroglyphic Egyptian texts are written in a literary prestige register rather than the vernacular speech variety of their author. As a result, dialectical differences are not apparent in written Egyptian until the adoption of the Coptic alphabet . Nevertheless, it is clear that these differences existed before the Coptic period. In one Late Egyptian letter (dated c.  1200 BC ),

4896-744: The FERC and others, reviews proposed pipeline projects in order to comply with the Clean Water Act , the National Environmental Policy Act , other laws and, in some cases, municipal laws. The Biden administration has sought to permit the respective states and tribal groups to appraise and potentially block the proposed projects. Field devices are instrumentation, data gathering units and communication systems. The field instrumentation includes flow, pressure, and temperature gauges/transmitters, and other devices to measure

4998-583: The Muslim conquest of Egypt , although Bohairic Coptic remains in use as the liturgical language of the Coptic Church . The Egyptian language branch belongs to the Afroasiatic language family . Among the typological features of Egyptian that are typically Afroasiatic are its fusional morphology, nonconcatenative morphology , a series of emphatic consonants , a three-vowel system /a i u/ ,

5100-566: The Ramessid tombs of Siese and Amenhotep . In Graeco-Roman times, there was a distinct dialect of Coptic spoken in Asyut, known as " Lycopolitan ", after the Greek name for the city. Lesser-used names for this dialect are "Sub-Akhmimic" and "Assiutic". A large Byzantine Treasure was discovered near the city in the early twentieth century and is now dispersed amongst a number of museums in

5202-573: The cathedral of the Mother of Divine Love, in Assyut. (all Coptic Rite ) Köppen-Geiger climate classification system classifies its climate as hot desert (BWh). It is the driest city of Egypt . Luxor , Minya , Qena and Asyut have the widest difference of temperatures between days and nights of any city in Egypt, with almost 16 °C (29 °F) difference. The city of Asyut is sandwiched between two mountain ranges of about 600m height. There

5304-588: The hieroglyphic and hieratic scripts. Demotic is the name of the script derived from the hieratic beginning in the 7th century BC. The Coptic alphabet was derived from the Greek alphabet , with adaptations for Egyptian phonology. It was first developed in the Ptolemaic period , and gradually replaced the Demotic script in about the 4th to 5th centuries of the Christian era. The term "Archaic Egyptian"

5406-697: The 14th century. Today, the city of Asyut has almost 400,000 inhabitants. It is the Egyptian city with one of the highest Coptic Christian concentrations of approximately 50%. It is also home to the Assiut University , one of the largest universities in Egypt , to the Assiut Barrage , and to the Lillian Trasher Orphanage . The city is one of the only cities in the world that still makes silver appliqué-work shawls and

5508-611: The Egyptian language shared closer linguistic ties with northeastern African regions. There are two theories that seek to establish the cognate sets between Egyptian and Afroasiatic, the traditional theory and the neuere Komparatistik , founded by Semiticist Otto Rössler. According to the neuere Komparatistik , in Egyptian, the Proto-Afroasiatic voiced consonants */d z ð/ developed into pharyngeal ⟨ꜥ⟩ /ʕ/ : Egyptian ꜥr.t 'portal', Semitic dalt 'door'. The traditional theory instead disputes

5610-544: The Nome formed the southern limits. The conflict between this Nome and the southern Nomes under the rule of the Eleventh Dynasty ended with the victory of Thebes and the decline of Asyut's importance. Lycopolis has no remarkable ruins, but in the excavated chambers of the adjacent rocks mummies of wolves have been found, confirming the origin of its name, as well as a tradition preserved by Diodorus Siculus , to

5712-471: The Russian-Ukrainian war, the submarine natural gas pipelines Nord Stream I and II got blasted. In general, pipelines can be classified in three categories depending on purpose: When a pipeline is built, the construction project not only covers the civil engineering work to lay the pipeline and build the pump/compressor stations, it also has to cover all the work related to the installation of

5814-598: The Savage River. Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure . Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, with transport costs similar to CNG , the technology is proven. Most hydrogen is produced at the place of demand with every 50 to 100 miles (160 km) an industrial production facility. The 1938 Rhine-Ruhr 240-kilometre (150 mi) hydrogen pipeline

5916-597: The Semitic preference for triradical roots. Egyptian is probably more conservative, and Semitic likely underwent later regularizations converting roots into the triradical pattern. Although Egyptian is the oldest Afroasiatic language documented in written form, its morphological repertoire is very different from that of the rest of the Afroasiatic languages in general, and Semitic languages in particular. There are multiple possibilities: perhaps Egyptian had already undergone radical changes from Proto-Afroasiatic before it

6018-533: The US. The distance from the biggest oil patch in North Dakota, in Williston, North Dakota , is only about 85 miles or 137 kilometers to the Canada–US border and Manitoba . Mutual funds and joint ventures are the largest investors in new oil and gas pipelines. In the fall of 2012, the US began exporting propane to Europe, known as LPG, as wholesale prices there are much higher than in North America. Additionally,

6120-554: The United States, 70% of crude oil and petroleum products are shipped by pipeline. (23% are by ship, 4% by truck, and 3% by rail) In Canada for natural gas and petroleum products, 97% are shipped by pipeline. Natural gas (and similar gaseous fuels) are lightly pressurized into liquids known as Natural Gas Liquids (NGLs). Small NGL processing facilities can be located in oil fields so the butane and propane liquid under light pressure of 125 pounds per square inch (860 kPa), can be shipped by rail, truck or pipeline. Propane can be used as

6222-510: The West. The hoard is composed of some of the most elaborate jewellery to survive from late antiquity . Asyut was at the end of the 40 Day Road that connected the city to Darfur through the Selima and Kharga Oases . The history of the road, known by local herders as Darb al-Arba'in , goes back over 700 years. It was used as a pathway for great caravans of up to 12,000 camels at its peak in

A three-kilometer beer pipeline was completed in Bruges , Belgium in September 2016 to reduce truck traffic on the city streets. The village of Hallstatt in Austria, which is known for its long history of salt mining , claims to contain "the oldest industrial pipeline in the world", dating back to 1595. It

6426-613: The definite article ⲡ is unaspirated when the next word begins with a glottal stop: Bohairic ⲡ + ⲱⲡ > ⲡⲱⲡ 'the account'. The consonant system of Coptic is as follows: Here is the vowel system reconstructed for earlier Egyptian: Vowels are always short in unstressed syllables ( ⟨tpj⟩ = */taˈpij/ 'first') and long in open stressed syllables ( ⟨rmṯ⟩ = */ˈraːmac/ 'man'), but they can be either short or long in closed stressed syllables ( ⟨jnn⟩ = */jaˈnan/ 'we', ⟨mn⟩ = */maːn/ 'to stay'). Oil pipeline A pipeline

6528-609: The economic downturn in 2008. After faltering in 2009, demand for pipeline expansion and updating increased the following year as energy production grew. By 2012, almost 32,000 miles (51500 km) of North American pipeline were being planned or under construction. When pipelines are constrained, additional pipeline product transportation options may include the use of drag reducing agents, or by transporting product via truck or rail. Oil pipelines are made from steel or plastic tubes with inner diameter typically from 4 to 48 inches (100 to 1,220 mm). Most pipelines are typically buried at

6630-475: The effect that an Ethiopian army, invading Egypt, was repelled beyond the city of Elephantine by packs of wolves. Osiris was worshipped under the symbol of a wolf at Lycopolis. According to a myth, he had come "from the shades" as a wolf to aid Isis and Horus in their combat with Typhon . Other ancient Egyptian monuments discovered in Asyut include; the Asyut necropolis (west of the modern city), tombs which date to dynasties Nine , Ten and Twelve , and

6732-637: The emphatic consonants were realised is unknown. Early research had assumed that the opposition in stops was one of voicing, but it is now thought to be either one of tenuis and emphatic consonants , as in many Semitic languages, or one of aspirated and ejective consonants , as in many Cushitic languages . Since vowels were not written until Coptic, reconstructions of the Egyptian vowel system are much more uncertain and rely mainly on evidence from Coptic and records of Egyptian words, especially proper nouns, in other languages/writing systems. The actual pronunciations reconstructed by such means are used only by

6834-439: The end of a stressed syllable and eventually null word-finally: ⟨pḏ.t⟩ */ˈpiːɟat/ > Akkadian transcription -pi-ta 'bow'. The most important source of information about Demotic phonology is Coptic. The consonant inventory of Demotic can be reconstructed on the basis of evidence from the Coptic dialects. Demotic orthography is relatively opaque . The Demotic "alphabetical" signs are mostly inherited from

6936-513: The field devices that will support remote operation. The pipeline is routed along what is known as a "right of way". Pipelines are generally developed and built using the following stages: Russia has "Pipeline Troops" as part of the Rear Services , who are trained to build and repair pipelines. Russia is the only country to have Pipeline Troops. The U.S. government, mainly through the EPA ,

7038-547: The first known Coptic text, still pagan ( Old Coptic ), from the 1st century AD. Coptic survived into the medieval period, but by the 16th century was dwindling rapidly due to the persecution of Coptic Christians under the Mamluks . It probably survived in the Egyptian countryside as a spoken language for several centuries after that. Coptic survives as the liturgical language of the Coptic Orthodox Church and

7140-588: The government regulated pipeline shipping charges because of the significantly shorter distance from gas source to consumer. To avoid delays and US government regulation, many small, medium and large oil producers in North Dakota have decided to run an oil pipeline north to Canada to meet up with a Canadian oil pipeline shipping oil from west to east. This allows the Bakken Basin and Three Forks oil producers to get higher negotiated prices for their oil because they will not be restricted to just one wholesale market in

7242-655: The graphemes ⟨s⟩ and ⟨z⟩ are used interchangeably. In addition, / j / had become / ʔ / word-initially in an unstressed syllable (⟨ jwn ⟩ /jaˈwin/ > */ʔaˈwin/ "colour") and after a stressed vowel ( ⟨ḥjpw⟩ */ˈħujpVw/ > /ˈħeʔp(Vw)/ '[the god] Apis'). In Late Egyptian (1069–700 BC), the phonemes d ḏ g gradually merge with their counterparts t ṯ k ( ⟨dbn⟩ */ˈdiːban/ > Akkadian transcription ti-ba-an 'dbn-weight'). Also, ṯ ḏ often become /t d/ , but they are retained in many lexemes ; ꜣ becomes / ʔ / ; and /t r j w/ become / ʔ / at

7344-435: The hieroglyphic orthography, and it is frequently written as if it were / n / or / r / . That is probably because the standard for written Egyptian is based on a dialect in which / l / had merged with other sonorants. Also, the rare cases of / ʔ / occurring are not represented. The phoneme / j / is written as ⟨ j ⟩ in the initial position (⟨ jt ⟩ = */ˈjaːtVj/ 'father') and immediately after

7446-519: The hieroglyphic script, and due to historical sound changes they do not always map neatly onto Demotic phonemes . However, the Demotic script does feature certain orthographic innovations, such as the use of the sign h̭ for / ç /, which allow it to represent sounds that were not present in earlier forms of Egyptian. The Demotic consonants can be divided into two primary classes: obstruents ( stops , affricates and fricatives ) and sonorants ( approximants , nasals , and semivowels ). Voice

7548-464: The language's final stage of development, the Coptic alphabet replaced the older writing system. Hieroglyphs are employed in two ways in Egyptian texts: as ideograms to represent the idea depicted by the pictures and, more commonly, as phonograms to represent their phonetic value. As the phonetic realization of Egyptian cannot be known with certainty, Egyptologists use a system of transliteration to denote each sound that could be represented by

7650-406: The latter of which it shares much with. In the earlier stages of Demotic, such as those texts written in the early Demotic script, it probably represented the spoken idiom of the time. However, as its use became increasingly confined to literary and religious purposes, the written language diverged more and more from the spoken form, leading to significant diglossia between the late Demotic texts and

7752-466: The lifeline of the Roman Empire. The ancient Chinese also made use of channels and pipe systems for public works. The famous Han dynasty court eunuch Zhang Rang (d. 189 AD) once ordered the engineer Bi Lan to construct a series of square-pallet chain pumps outside the capital city of Luoyang . These chain pumps serviced the imperial palaces and living quarters of the capital city as

7854-416: The mainland. In 1994, the pipeline was abandoned. In places, a pipeline may have to cross water expanses, such as small seas, straits and rivers. In many instances, they lie entirely on the seabed. These pipelines are referred to as "marine" pipelines (also, "submarine" or "offshore" pipelines). They are used primarily to carry oil or gas, but transportation of water is also important. In offshore projects,

7956-413: The most economical way to transport large quantities of oil, refined oil products or natural gas over land. For example, in 2014, pipeline transport of crude oil cost about $ 5 per barrel, while rail transport cost about $ 10 to $ 15 per barrel. Trucking has even higher costs due to the additional labor required; employment on completed pipelines represents only "1% of that of the trucking industry.". In

8058-474: The neighboring port of Al-Hamra . The dam was built in 1902 and a hydroelectric plant was added in the 1980s. On 10 August 1947, a Coptic Catholic eparchy ( Eastern Catholic Diocese) of Assiut (or Lycopolis) was established on southern Egyptian territory split off from the Coptic Catholic Eparchy of Luqsor , each suffragan of Coptic Catholic Patriarch of Alexandria . Its episcopal see is

8160-420: The night and frost can easily form, while hail or snow are rare because of the low average of the city's precipitation and general low humidity . The highest record temperature was 51 °C (124 °F), recorded on July 23, 1994, while the lowest record temperature was −2 °C (28 °F), recorded on January 16, 2008. The Alexan Pasha Palace was constructed in 1910 as a riverside residence of

8262-526: The oil to the market that gives the best price, and rail cars can be used to avoid a congested oil pipeline to get the oil to a different pipeline in order to get the oil to market faster or to a different less busy oil refinery. However, pipelines provide a cheaper means to transport by volume. Enbridge in Canada is applying to reverse an oil pipeline going from east-to-west (Line 9) and expanding it and using it to ship western Canadian bitumen oil eastward. From

8364-451: The operation, operator training requirements, pipeline facilities, technology and applications required to ensure operational safety. For example, in the State of Washington it is mandatory for pipeline operators to be able to detect and locate leaks of 8 percent of maximum flow within fifteen minutes or less. Social factors also affect the operation of pipelines. Product theft is sometimes also

8466-422: The pipeline to be received at any other station down-stream, either cleaning wax deposits and material that may have accumulated inside the line or inspecting and recording the condition of the line. For natural gas, pipelines are constructed of carbon steel and vary in size from 2 to 60 inches (51 to 1,524 mm) in diameter, depending on the type of pipeline. The gas is pressurized by compressor stations and

8568-512: The quality of the surrounding vowels. / ʔ / is not indicated orthographically unless it follows a stressed vowel; then, it is marked by doubling the vowel letter (except in Bohairic): Akhmimic ⳉⲟⲟⲡ /xoʔp/ , Sahidic and Lycopolitan ϣⲟⲟⲡ šoʔp , Bohairic ϣⲟⲡ šoʔp 'to be' < ḫpr.w * /ˈχapraw/ 'has become'. The phoneme ⲃ / b / was probably pronounced as a fricative [ β ] , becoming ⲡ / p / after

8670-870: The reality" that the geographical location of Egypt is, of course, in Africa. While the consonantal phonology of the Egyptian language may be reconstructed, the exact phonetics is unknown, and there are varying opinions on how to classify the individual phonemes. In addition, because Egyptian is recorded over a full 2,000 years, the Archaic and Late stages being separated by the amount of time that separates Old Latin from Modern Italian , significant phonetic changes must have occurred during that lengthy time frame. Phonologically, Egyptian contrasted labial, alveolar, palatal, velar, uvular, pharyngeal, and glottal consonants. Egyptian also contrasted voiceless and emphatic consonants, as with other Afroasiatic languages, but exactly how

8772-584: The relevant data required. These instruments are installed along the pipeline on some specific locations, such as injection or delivery stations, pump stations (liquid pipelines) or compressor stations (gas pipelines), and block valve stations. The information measured by these field instruments is then gathered in local remote terminal units (RTU) that transfer the field data to a central location in real time using communication systems, such as satellite channels, microwave links, or cellular phone connections. Pipelines are controlled and operated remotely, from what

8874-599: The same graphemes are used for the pulmonic stops ( ⟨ ⲧ ϫ ⲕ ⟩ ), the existence of the former may be inferred because the stops ⟨ ⲡ ⲧ ϫ ⲕ ⟩ /p t c k/ are allophonically aspirated [pʰ tʰ cʰ kʰ] before stressed vowels and sonorant consonants. In Bohairic, the allophones are written with the special graphemes ⟨ ⲫ ⲑ ϭ ⲭ ⟩ , but other dialects did not mark aspiration: Sahidic ⲡⲣⲏ , Bohairic ⲫⲣⲏ 'the sun'. Thus, Bohairic does not mark aspiration for reflexes of older *d ḏ g q : Sahidic and Bohairic ⲧⲁⲡ */dib/ 'horn'. Also,

8976-433: The script was supplanted by an early version of Coptic (about the third and fourth centuries), the system remained virtually unchanged. Even the number of signs used remained constant at about 700 for more than 2,000 years. Middle Egyptian was spoken for about 700 years, beginning around 2000 BC, during the Middle Kingdom and the subsequent Second Intermediate Period . As the classical variant of Egyptian, Middle Egyptian

9078-445: The sea, that process is economically and technically demanding, so the majority of oil at sea is transported by tanker ships . Similarly, it is often more economically feasible to transport natural gas in the form of LNG, however the break-even point between LNG and pipelines would depend on the volume of natural gas and the distance it travels. The market size for oil and gas pipeline construction experienced tremendous growth prior to

9180-480: The southern Saidic dialect, the main classical dialect, and the northern Bohairic dialect, currently used in Coptic Church services. Most surviving texts in the Egyptian language are written on stone in hieroglyphs . The native name for Egyptian hieroglyphic writing is zẖꜣ n mdw-nṯr ("writing of the gods' words"). In antiquity, most texts were written on the quite perishable medium of papyrus though

9282-567: The spoken language of the time, similar to the use of classical Middle Egyptian during the Ptolemaic Period. Coptic is the name given to the late Egyptian vernacular when it was written in a Greek-based alphabet, the Coptic alphabet; it flourished from the time of Early Christianity (c. 31/33–324) , but Egyptian phrases written in the Greek alphabet first appeared during the Hellenistic period c.  3rd century BC , with

9384-615: The target of military attacks. It is well documented when the first crude oil pipeline was built. Credit for the development of pipeline transport belongs indisputably to the Oil Transport Association, which first constructed a 2-inch (51 mm) wrought iron pipeline over a 6-mile (9.7 km) track from an oil field in Pennsylvania to a railroad station in Oil Creek , in the 1860s. Pipelines are generally

9486-462: The transport of ethanol by pipeline are its corrosive nature and tendency to absorb water and impurities in pipelines, which are not problems with oil and natural gas. Insufficient volumes and cost-effectiveness are other considerations limiting construction of ethanol pipelines. In the US minimal amounts of ethanol are transported by pipeline. Most ethanol is shipped by rail, the main alternatives being truck and barge. Delivering ethanol by pipeline

9588-644: The values given to those consonants by the neuere Komparatistik , instead connecting ⟨ꜥ⟩ with Semitic /ʕ/ and /ɣ/ . Both schools agree that Afroasiatic */l/ merged with Egyptian ⟨n⟩ , ⟨r⟩ , ⟨ꜣ⟩ , and ⟨j⟩ in the dialect on which the written language was based, but it was preserved in other Egyptian varieties. They also agree that original */k g ḳ/ palatalise to ⟨ṯ j ḏ⟩ in some environments and are preserved as ⟨k g q⟩ in others. The Egyptian language has many biradical and perhaps monoradical roots, in contrast to

9690-557: The water lifted by the chain pumps was brought in by a stoneware pipe system. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills , or where canals or channels are poor choices due to considerations of evaporation , pollution , or environmental impact. The 530 km (330 miles) Goldfields Water Supply Scheme in Western Australia using 750 mm (30 inch) pipe and completed in 1903

9792-509: Was constructed from 13,000 hollowed-out tree trunks to transport brine 40 kilometres (25 mi) from Hallstatt to Ebensee . Between 1978 and 1994, a 15 km milk pipeline ran between the Dutch island of Ameland and Holwerd on the mainland, of which 8 km was beneath the Wadden Sea . Every day, 30,000 litres of milk produced on the island were transported to be processed on

9894-428: Was published by Adolf Erman in 1894, surpassed in 1927 by Alan Gardiner 's work. Middle Egyptian has been well-understood since then, although certain points of the verbal inflection remained open to revision until the mid-20th century, notably due to the contributions of Hans Jakob Polotsky . The Middle Egyptian stage is taken to have ended around the 14th century BC, giving rise to Late Egyptian. This transition

9996-479: Was recorded; or the Afroasiatic family has so far been studied with an excessively Semitocentric approach; or, as G. W. Tsereteli suggests, Afroasiatic is a sprachbund , rather than a true genetic language family. The Egyptian language can be grouped thus: The Egyptian language is conventionally grouped into six major chronological divisions: Old, Middle, and Late Egyptian were all written using both

10098-530: Was taking place in the later period of the Eighteenth Dynasty of Egypt (known as the Amarna Period ). Original Old Egyptian and Middle Egyptian texts were still used after the 14th century BCE. And an emulation of predominately Middle Egyptian, but also with characteristics of Old Egyptian, Late Egyptian and Demotic, called " Égyptien de tradition " or "Neo-Middle Egyptian" by scholars,

10200-680: Was the capital of the Thirteenth Nome of Upper Egypt ( Lycopolites Nome ) around 3100 BC. It was located on the western bank of the Nile . The two most prominent gods of ancient Egyptian Asyut were Anubis and Wepwawet , both funerary deities. During the First Intermediate Period , the rulers of " Zawty " ( Khety I , Tefibi , and Khety II ) were supporters of the Herakleopolitan kings, of whose domain

10302-987: Was the largest water supply scheme of its time. Examples of significant water pipelines in South Australia are the Morgan-Whyalla pipeline (completed 1944) and Mannum-Adelaide pipeline (completed 1955) pipelines, both part of the larger Snowy Mountains scheme . There are two Los Angeles, California aqueducts, the Owens Valley aqueduct (completed 1913) and the Second Los Angeles Aqueduct (completed 1970) which also include extensive use of pipelines. The Great Manmade River of Libya supplies 3,680,000 cubic metres (4,810,000 cu yd) of water each day to Tripoli, Benghazi, Sirte, and several other cities in Libya. The pipeline

10404-606: Was used as a literary language for new texts since the later New Kingdom in official and religious hieroglyphic and hieratic texts in preference to Late Egyptian or Demotic. Égyptien de tradition as a religious language survived until the Christianisation of Roman Egypt in the 4th century. Late Egyptian was spoken for about 650 years, beginning around 1350 BC, during the New Kingdom of Egypt . Late Egyptian succeeded but did not fully supplant Middle Egyptian as
