Saqiyah
A sāqiyah or saqiya (), also spelled sakia or saqia) is a mechanical water lifting device. It is also called a Persian wheel, tablia, rehat, and in Latin tympanum. It is similar in function to a scoop wheel, which uses buckets, jars, or scoops fastened either directly to a vertical wheel, or to an endless belt activated by such a wheel. The vertical wheel is itself attached by a drive shaft to a horizontal wheel, which is traditionally set in motion by animal power (oxen, donkeys, etc.) Because it is not using hydropower, the power of flowing water, the sāqiyah is different from a noria and any other type of water wheel. The sāqiyah is still used in India, Egypt and other parts of the Middle East, and in the Iberian Peninsula and the Balearic Islands. It may have been invented in Ptolemaic Kingdom of Egypt, Iran, Kingdom of Kush, Kush or India. The sāqiyah was mainly used for irrigation, but not exclusively, as the example of Qusayr 'Amra shows, where it was used at least in ...

Noria
A noria (, ''nā‘ūra'', plural ''nawāʿīr'', from , ''nā‘orā'', lit. "growler") is a hydropowered '' scoop wheel'' used to lift water into a small aqueduct, either for the purpose of irrigation or to supply water to cities and villages. Name and meaning Etymology The English word ''noria'' is derived via Spanish ''noria'' from Arabic ''nā‘ūra'' (ناعورة), which comes from the Arabic verb meaning to "groan" or "grunt", in reference to the sound it made when turning. ''Noria'' versus ''saqiyah'' The term ''noria'' is commonly used for devices which use the power of moving water to turn the wheel. For devices powered by animals, the usual term is '' saqiyah'' or ''saqiya''. Other types of similar devices are grouped under the name of chain pumps. However, the names of traditional water-raising devices used in the Middle East, India, Spain and other areas are often used loosely and overlappingly, or vary depending on region.

Kingdom Of Kush
The Kingdom of Kush (; Egyptian language, Egyptian: 𓎡𓄿𓈙𓈉 ''kꜣš'', Akkadian language, Assyrian: ''Kûsi'', in LXX Χους or Αἰθιοπία; ''Ecōš''; ''Kūš''), also known as the Kushite Empire, or simply Kush, was an ancient kingdom in Nubia, centered along the Nile Valley in what is now northern Sudan and southern Egypt. The region of Nubia was an early cradle of civilization, producing several complex societies that engaged in trade and industry. The city-state of Kerma emerged as the dominant political force between 2450 and 1450 BC, controlling the Nile Valley between the first and fourth Cataracts of the Nile, cataracts, an area as large as Egypt. The Egyptians were the first to identify Kerma as "Kush" probably from the indigenous ethnonym "Kasu", over the next several centuries the two civilizations engaged in intermittent warfare, trade, and cultural exchange. Much of Nubia came under Egyptian rule during the New Kingdom of Egypt, New Kingdom pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acequia
An acequia () or (, also known as síquia , all from ) is a community-operated watercourse used in Spain and former Spanish colonies in the Americas for irrigation. Acequias are found in parts of Spain, the Andes, northern Mexico, and what is now the Southwestern United States (northern New Mexico and southern Colorado). In the United States, the oldest known irrigation canals are in Arizona and date back to 1200 BCE. Irrigation was extensively used by the Pueblo peoples in New Mexico in the Pre-Columbian era. Spanish colonizers arrived in New Mexico in 1598 and brought irrigation methods from Iberia based on the Arab Agricultural Revolution. Scholars describe acequias as "technological systems that are designed, maintained, and operated to meet a variety of productive goals, social services, and health needs, with the practice of irrigated agriculture being of paramount importance." The traditional form of governance over acequias survives in New Mexico and southern Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The "Persian Wheel
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

Working Animal
A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons, and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather. The history of working animals may predate agriculture as dogs were used by hunter-gatherer ancestors; around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and some Asian elephants. People have found uses for a wide variety of abili ...

Hot-dip Galvanizing
Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around . When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (Oxygen, O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2, CO2) to form zinc carbonate (Smithsonite, ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle. It can be identified by the crystallization patterning on the surface (often called a "spangle"). Galvanized steel can be welded; however, one must exercise caution around the resulting toxic zinc fumes. Galvanized fumes are released when the ga ...
