Haditha Dam
The Haditha Dam ( ar, سد حديثة, Sadd Ḥadītha) or Qadisiya Dam is an earth-fill dam on the Euphrates, north of Haditha (Iraq), creating Lake Qadisiyah ( ar, script=Latn, Buhayrat al-Qadisiyyah). The dam is just over long and high. The purpose of the dam is to generate hydroelectricity, regulate the flow of the Euphrates and provide water for irrigation. It is the second-largest hydroelectric contributor to the power system in Iraq behind the Mosul Dam. Project history The Haditha Dam project was conceived in the late 1960s; construction began in 1977. The dam embankment was designed by the Soviet Union's Ministry of Energy, with its power station and equipment being designed and constructed by various Yugoslavian firms; these included Hidrogradnja of Sarajevo, as the prime contractor; Energoprojekt of Belgrade for design; Metalna of Maribor for intake gates, bottom outlet gate, radial gates; Litostroj of Ljubljana for turbines; and Rade Končar of Zagreb for gene ...

Belgrade
Belgrade ( , ;, ; names in other languages) is the capital and largest city in Serbia. It is located at the confluence of the Sava and Danube rivers and the crossroads of the Pannonian Plain and the Balkan Peninsula. Nearly 1,166,763 million people live within the administrative limits of the City of Belgrade. It is the third largest of all cities on the Danube river. Belgrade is one of the oldest continuously inhabited cities in Europe and the world. One of the most important prehistoric cultures of Europe, the Vinča culture, evolved within the Belgrade area in the 6th millennium BC. In antiquity, Thraco- Dacians inhabited the region and, after 279 BC, Celts settled the city, naming it '' Singidūn''. It was conquered by the Romans under the reign of Augustus and awarded Roman city rights in the mid-2nd century. It was settled by the Slavs in the 520s, and changed hands several times between the Byzantine Empire, the Frankish Empire, the Bulgarian Empire, and ...

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] |
Terracotta
Terracotta, terra cotta, or terra-cotta (; ; ), in its material sense as an earthenware substrate, is a clay-based unglazed or glazed ceramic where the fired body is porous. In applied art, craft, construction, and architecture, terracotta is the term normally used for sculpture made in earthenware and also for various practical uses, including vessels (notably flower pots), water and waste water pipes, roofing tiles, bricks, and surface embellishment in building construction. The term is also used to refer to the natural brownish orange color of most terracotta. In archaeology and art history, "terracotta" is often used to describe objects such as figurines not made on a potter's wheel. Vessels and other objects that are or might be made on a wheel from the same material are called earthenware pottery; the choice of term depends on the type of object rather than the material or firing technique. Unglazed pieces, and those made for building construction and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anah
Anah or Ana ( ar, عانة, ''ʾĀna'', syr, ܐܢܐ), formerly also known as Anna, is an Iraqi town on the Euphrates river, approximately midway between the Gulf of Alexandretta and the Persian Gulf. Anah lies from west to east on the right bank along a bend of the river just before it turns south towards Hit. Name The town was called (d)Ha-na-at in cuneiform texts from the Old Babylonian period, A-na-at by the scribes of Tukulti-Ninurta BC, and An-at by the scribes of Assur-nasir-pal II in 879 BC. The name has been connected with the widely worshipped war goddess Anat. It was known as ''Anathō'' ( grc-gre, Άναθω) to Isidore Charax and ' to Ammianus Marcellinus; early Arabic writers described it variously as ''ʾĀna'' or (as if plural) ''ʾĀnāt''. History Middle Bronze The earliest references to Anah are probably found in letters of the period of Zimri-Lim of Mari. Under Hammurapi of Babylon the town was under Babylonian control, being included in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. Since the invention of the first constant-potential trans ...

Electric Generator
In electricity generation, a generator is a device that converts motive power ( mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electro ...

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβ ...
