Salsabil (Quran)
Salsabil ( ar, سلسبيل, romanized as ', ', ', ', ', ') is an Arabic term referring to a spring or fountain in paradise, mentioned in the Qur'an and in some hadiths. The term is also used as a common and proper noun. In the Quran In the Quran, the word is used once, to refer to a spring or fountain in paradise (Jannah). The sole quranic reference is in sura Al-Insan. There is also mention in some hadith. The verse may be in reference to the previous verse concerning the drink provided to those who enter paradise. "Salsabil" is usually but not always considered to be used as a proper noun, not a common noun, in this verse (that is, the capitalized name of one specific water source). The common noun is used in Hindustani to mean " nning limpid, sweet water", and in Persian for a pleasant beverage. Derivations The Qur'anic term is probably the source of the engineering use of "salsabil", to mean a device for aerating drinking water in a sebil. The word is also used to ...

Romanization
Romanization or romanisation, in linguistics, is the conversion of text from a different writing system to the Roman (Latin) script, or a system for doing so. Methods of romanization include transliteration, for representing written text, and transcription, for representing the spoken word, and combinations of both. Transcription methods can be subdivided into ''phonemic transcription'', which records the phonemes or units of semantic meaning in speech, and more strict ''phonetic transcription'', which records speech sounds with precision. Methods There are many consistent or standardized romanization systems. They can be classified by their characteristics. A particular system’s characteristics may make it better-suited for various, sometimes contradictory applications, including document retrieval, linguistic analysis, easy readability, faithful representation of pronunciation. * Source, or donor language – A system may be tailored to romanize text from a particular lan ...

Wudu
Wuḍūʾ ( ar, الوضوء ' ) is the Islamic procedure for cleansing parts of the body, a type of ritual purification, or ablution. The 4 Fardh (Mandatory) acts of ''Wudu'' consists of washing the face, arms, then wiping the head and the feet with water. Wudu is an important part of ritual purity in Islam. It is governed by ''fiqh'' (Islamic jurisprudence), which specifies rules concerning hygiene and defines the rituals that constitute it. It is typically performed before prayers ('' salah or salat''). Activities that invalidate ''wudu'' include urination, defecation, flatulence, deep sleep, light bleeding, menstruation, postpartum and sexual intercourse. ''Wudu'' is often translated as 'partial ablution', as opposed to '' ghusl'' as 'full ablution' where the whole body is washed. It also contrasts with ''tayammum'' ('dry ablution'), which uses sand or dust in place of water, principally due to water scarcity or other harmful effects on the person. Purification of the bod ...

Sebil
A sebil or sabil ( ar, سبيل, sabīl ; Turkish: ''sebil'') is a small kiosk in the Islamic architectural tradition where water is freely dispensed to members of the public by an attendant behind a grilled window. The term is sometimes also used to refer to simple unmanned fountains with a tap for drinking water, though other names often exist for such fountains (such as ''çesme'' in Turkish). Historically, sebils are structures of both civic and religious importance in Muslim cities, most prominently in the cities of the Ottoman Empire, based in Istanbul, and of the Mamluk Empire, based in Cairo. They were built at crossroads, in the middle of city squares, and on the outside of mosques and other religious complexes to provide drinking water for travelers and to assist ritual purification (ablutions) before prayer. Etymology The word ''sebil'' or ''sabil'' comes from the Arabic verb root ''sabala'' (سبل) meaning "to let fall, drop, to let hang down, to close eyes or ...

Salsabil (fountain)
A salsabil (or salasabil), also known as a shadirwan, is a type of fountain which maximizes the surface area of the water. It is used for evaporative cooling of buildings, cooling and aeration of drinking water, and ornament (it has also been used to prevent eavesdropping). The water may flow in a thin sheet or thin streams, often over a wavy surface with many little waterfalls. Its use extends from southern Spain through north Africa and the Middle East to northern India. Etymology and name The name ''salsabil'' likely derives from a Qur'anic reference. The term ''shadirwan'' is also used for devices for aerating drinking water. However, the term ''shadirwan'' or ''shadirvan'' has slightly different uses in other cultures, such as designating a central ablutions fountain for a mosque courtyard in Turkish (see ''shadirvan''). Design and setting The water flows in a manner designed to maximize the surface area, and thus evaporation. A salsabil may be a near-vertical marble ...

Tehran
Tehran (; fa, تهران ) is the largest city in Tehran Province and the capital of Iran. With a population of around 9 million in the city and around 16 million in the larger metropolitan area of Greater Tehran, Tehran is the most populous city in Iran and Western Asia, and has the second-largest metropolitan area in the Middle East, after Cairo. It is ranked 24th in the world by metropolitan area population. In the Classical era, part of the territory of present-day Tehran was occupied by Rhages, a prominent Median city destroyed in the medieval Arab, Turkic, and Mongol invasions. Modern Ray is an urban area absorbed into the metropolitan area of Greater Tehran. Tehran was first chosen as the capital of Iran by Agha Mohammad Khan of the Qajar dynasty in 1786, because of its proximity to Iran's territories in the Caucasus, then separated from Iran in the Russo-Iranian Wars, to avoid the vying factions of the previously ruling Iranian dynasties. The capital has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Salsabil, Tehran, Tehran Province, Iran - Panoramio
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations.

Evaporative Cooling
An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling exploits the fact that water will absorb a relatively large amount of heat in order to evaporate (that is, it has a large enthalpy of vaporization). The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants. The cooling potential for evaporative cooling is dependent on the wet-bulb depression, the difference between dry-bulb temperature and wet-bulb temperature ...

Water Aeration
Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments. Aeration techniques are commonly used in pond, lake, and reservoir management to address low oxygen levels or algal blooms. Water quality Water aeration is often required in water bodies that suffer from Hypoxia (environmental), hypoxic or anoxic conditions, often caused by upstream human activities such as sewage discharges, agricultural run-off, or over-baiting a fishing lake. Aeration can be achieved through the infusion of air into the bottom of the lake, lagoon or pond or by surface agitation from a fountain or spray-like device to allow for oxygen exchange at the surface and the release of gasses such as carbon dioxide, methane or hydrogen sulfide. Decreased levels of dissolved oxygen (DO) is a major contributor to poor water quality. Not only do fish and most other aquatic animals need oxygen, aerobic bacteria help decompose organic matter ...
