Nagina Mosque
Nagina Mosque (meaning 'Jewel Mosque', see Negin) is a mosque in Champaner, Gujarat, India. It was built during the time of Mahmud Begada, in the 15th century, as were several other masjids, such as the Kevada, Bawaman, Ek Minar, Jama, Khajuri, and Shahar Ki. It has minarets, globe-like domes, and narrow stairs. It is part of the Champaner-Pavagadh Archaeological Park, a UNESCO World Heritage Site. Geography The masjid is about to the south of the citadel, and north of the ''Bhadr''. The Kajuri Masjid is west of the Nagina and the Kevada is to the north-northwest. A small lake is situated considerably to the north. After James Burgess and Henry Cousens wrote descriptions of the Nagina, Kevada, and Jama Masjids, roads were built to reach them.

World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. ...

Ferrous Salt
Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO4·''x''H2O. These compounds exist most commonly as the hepta hydrate (''x'' = 7) but several values for x are known. The hydrated form is used medically to treat iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol (vitriol is an archaic name for sulfate), the blue-green heptahydrate ( hydrate with 7 molecules of water) is the most common form of this material. All the iron(II) sulfates dissolve in water to give the same aquo complex e(H2O)6sup>2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas. It is on the World Health Organization's List of Essential Medicines. In 2020, it was the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Hexametaphosphate
Sodium hexametaphosphate (SHMP) is a salt of composition Na6 PO3)6 Sodium hexametaphosphate of commerce is typically a mixture of metaphosphates (empirical formula: NaPO3), of which the hexamer is one, and is usually the compound referred to by this name. Such a mixture is more correctly termed sodium polymetaphosphate. They are white solids that dissolve in water. Uses SHMP is used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the E number E452i. Sodium carbonate is sometimes added to SHMP to raise the pH to 8.0–8.6, which produces a number of SHMP products used for water softening and detergents. A significant use for sodium hexametaphosphate is as a deflocculant in the production of clay-based ceramic particles. It is also used as a dispersing agent to break down clay and other soil types for soil texture assessment. It is used as an active ingredient in toothpastes as an anti-staining a ...

Ethyl Silicate
Tetraethyl orthosilicate, formally named tetraethoxysilane (TEOS), ethyl silicate is the organic chemical compound with the formula Si(OC2H5)4. TEOS is a colorless liquid. It degrades in water. TEOS is the of orthosilicic acid, Si(OH)4. It is the most prevalent alkoxide of silicon. TEOS is a tetrahedral molecule. Like its many analogues, it is prepared by alcoholysis of silicon tetrachloride: :SiCl4 + 4 EtOH → Si(OEt)4 + 4 HCl where Et is the ethyl group, C2H5, and thus EtOH is ethanol. Applications TEOS is mainly used as a crosslinking agent in silicone polymers and as a precursor to silicon dioxide in the semiconductor industry. TEOS is also used as the silica source for synthesis of some zeolites. Other applications include coatings for carpets and other objects. TEOS is used in the production of aerogel. These applications exploit the reactivity of the Si-OR bonds. TEOS has historically been used as an additive to alcohol based rocket fuels to decrease the h ...

Cenotaph
A cenotaph is an empty tomb or a monument erected in honour of a person or group of people whose remains are elsewhere. It can also be the initial tomb for a person who has since been reinterred elsewhere. Although the vast majority of cenotaphs honour individuals, many noted cenotaphs are instead dedicated to the memories of groups of individuals, such as the lost soldiers of a country or of an empire. Etymology The word "cenotaph" in the English Language is derived from the Greek el, κενοτάφιον, kenotaphion, label=none. It is a compound word that is created from the morphological combination of two root words: # el, κενός, kenos, label=none meaning "empty" # el, τάφος, taphos, label=none meaning "tomb", from el, θαπτω, thapto, I bury, label=none History Cenotaphs were common in the ancient world. Many were built in Ancient Egypt, Ancient Greece and across Northern Europe (in the shape of Neolithic barrows). The cenotaph in Whitehall, Lo ...

Mausoleum
A mausoleum is an external free-standing building constructed as a monument enclosing the interment space or burial chamber of a deceased person or people. A mausoleum without the person's remains is called a cenotaph. A mausoleum may be considered a type of tomb, or the tomb may be considered to be within the mausoleum. Overview The word ''mausoleum'' (from Greek μαυσωλείον) derives from the Mausoleum at Halicarnassus (near modern-day Bodrum in Turkey), the grave of King Mausolus, the Persian satrap of Caria, whose large tomb was one of the Seven Wonders of the Ancient World. Historically, mausolea were, and still may be, large and impressive constructions for a deceased leader or other person of importance. However, smaller mausolea soon became popular with the gentry and nobility in many countries. In the Roman Empire, these were often in necropoles or along roadsides: the via Appia Antica retains the ruins of many private mausolea for kilometres outside Rome ...

Step Well
Stepwells (also known as vavs or baori) are wells or ponds with a long corridor of steps that descend to the water level. Stepwells played a significant role in defining subterranean architecture in western India from 7th to 19th century. Some stepwells are multi-storeyed and can be accessed by a Persian wheel which is pulled by a bull to bring water to the first or second floor. They are most common in western India and are also found in the other more arid regions of the Indian subcontinent, extending into Pakistan. The construction of stepwells is mainly utilitarian, though they may include embellishments of architectural significance, and be temple tanks. Stepwells are examples of the many types of storage and irrigation tanks that were developed in India, mainly to cope with seasonal fluctuations in water availability. A basic difference between stepwells on the one hand, and tanks and wells on the other, is that stepwells make it easier for people to reach the groundwat ...

Cornice
In architecture, a cornice (from the Italian ''cornice'' meaning "ledge") is generally any horizontal decorative moulding that crowns a building or furniture element—for example, the cornice over a door or window, around the top edge of a pedestal, or along the top of an interior wall. A simple cornice may be formed just with a crown, as in crown moulding atop an interior wall or above kitchen cabinets or a bookcase. A projecting cornice on a building has the function of throwing rainwater free of its walls. In residential building practice, this function is handled by projecting gable ends, roof eaves and gutters. However, house eaves may also be called "cornices" if they are finished with decorative moulding. In this sense, while most cornices are also eaves (overhanging the sides of the building), not all eaves are usually considered cornices. Eaves are primarily functional and not necessarily decorative, while cornices have a decorative aspect. A building's projectin ...

Corbel
In architecture, a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure. A piece of timber projecting in the same way was called a "tassel" or a "bragger" in England. The technique of corbelling, where rows of corbels deeply keyed inside a wall support a projecting wall or parapet, has been used since Neolithic (New Stone Age) times. It is common in medieval architecture and in the Scottish baronial style as well as in the vocabulary of classical architecture, such as the modillions of a Corinthian cornice. The corbel arch and corbel vault use the technique systematically to make openings in walls and to form ceilings. These are found in the early architecture of most cultures, from Eurasia to Pre-Columbian architecture. A console is more specifically an "S"-shaped scroll bracket in the classica ...

Minaret
A minaret (; ar, منارة, translit=manāra, or ar, مِئْذَنة, translit=miʾḏana, links=no; tr, minare; fa, گلدسته, translit=goldaste) is a type of tower typically built into or adjacent to mosques. Minarets are generally used to project the Muslim call to prayer (''adhan''), but they also served as landmarks and symbols of Islam's presence. They can have a variety of forms, from thick, squat towers to soaring, pencil-thin spires. Etymology Two Arabic words are used to denote the minaret tower: ''manāra'' and ''manār''. The English word "minaret" originates from the former, via the Turkish version (). The Arabic word ''manāra'' (plural: ''manārāt'') originally meant a "lamp stand", a cognate of Hebrew '' menorah''. It is assumed to be a derivation of an older reconstructed form, ''manwara''. The other word, ''manār'' (plural: ''manā'ir'' or ''manāyir''), means "a place of light". Both words derive from the Arabic root ''n-w-r'', which has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
