Shabestan
A shabestan or shabistan ( fa, ; Old Persian ''xšapā.stāna'') is an underground space that can be usually found in traditional architecture of mosques, houses, and schools in ancient Iran. These spaces were usually used during summers and could be ventilated by windcatchers and qanats. During the Sasanian Empire and the subsequent Islamic periods, "shabestan" also referred to inner sanctums of the shahs where their concubines resided. Later these structures came to be called '' zanāneh'' (feminine residence), ''andaruni'' (inner private zone) and ''haram'' (from Arabic harem). Cooling A shabestan can be cooled using a qanat in conjunction with a windcatcher. A windcatcher is a chimney-like structure positioned above the house; the one of its four openings opposite the wind direction is opened to move air out of the house. Incoming air is pulled from a qanat below the house. The air flow across the vertical shaft opening creates a lower pressure (see Bernoulli effect) and ...

Windcatcher
A windcatcher, wind tower, or wind scoop ( ar, برجيل ; fa, بادگیر) is a traditional architectural element used to create cross ventilation and passive cooling in buildings. Windcatchers come in various designs: unidirectional, bidirectional, and multidirectional. Windcatchers are widely used in North Africa and West Asia. Iran, especially in the south of Fars province and Hormozgan province, and other countries around the Persian Gulf have used windcatchers for the past three thousand years. Neglected by modern architects in the latter half of the 20th century, the early 21st century saw them used again, to increase ventilation and cut power demand for air-conditioning. Generally, the cost of construction for a windcatcher-ventilated building is less than that of a similar building with conventional heating, ventilation, and air conditioning (HVAC) systems. The maintenance costs are also lower. Unlike powered air-conditioning and fans, windcatchers are silent and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qanat
A qanat or kārīz is a system for transporting water from an aquifer or water well to the surface, through an underground aqueduct; the system originated approximately 3,000 BC in what is now Iran. The function is essentially the same across North Africa and the Middle East but the system operates under a variety of regional names: ''qanat'' or kārīz in Iran, ''foggara'' in Algeria, ''khettara'' in Morocco, ''falaj'' in Oman, ''karez'' in Afghanistan, ''auyoun'' in Saudi Arabia, et al. The largest extant and functional qanat systems are located in Iran, Afghanistan, Oman, the oases of Turfan region of China, Algeria, and Pakistan. This is a system of water supply that allows water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. The system has the advantage of being resistant to natural disasters such as earthquakes and floods, and to deliberate destruction in war. Furthermore, it is almost insensitive to the level ...

Dehkhoda Dictionary
The ''Dehkhoda Dictionary'' ( fa, لغتنامهٔ دهخدا) is the largest comprehensive Persian encyclopedic dictionary ever published, comprising 200 volumes. It is published by the Tehran University Press (UTP) under the supervision of the Dehkhoda Dictionary Institute. It was first published in 1931. It traces the historical development of the Persian language, providing a comprehensive resource to scholars and academic researchers, as well as describing usage in its many variations throughout the world. The complete work is an ongoing effort that has taken over forty-five years of effort by Ali-Akbar Dehkhoda and a cadre of other experts. Although ''Dehkhoda'' covers a big part of literary terms and words in Persian, the first edition of it lacks most scientific and technology terms coined by the Academy of Persian Language and Literature during the past decades. However the newer editions cover them. Dehkhoda states in the preface of the first edition of the dictio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islamic Architectural Elements
Islam (; ar, ۘالِإسلَام, , ) is an Abrahamic monotheistic religion centred primarily around the Quran, a religious text considered by Muslims to be the direct word of God (or ''Allah'') as it was revealed to Muhammad, the main and final Islamic prophet.Peters, F. E. 2009. "Allāh." In , edited by J. L. Esposito. Oxford: Oxford University Press. . (See alsoquick reference) " e Muslims' understanding of Allāh is based...on the Qurʿān's public witness. Allāh is Unique, the Creator, Sovereign, and Judge of mankind. It is Allāh who directs the universe through his direct action on nature and who has guided human history through his prophets, Abraham, with whom he made his covenant, Moses/Moosa, Jesus/Eesa, and Muḥammad, through all of whom he founded his chosen communities, the 'Peoples of the Book.'" It is the world's second-largest religion behind Christianity, with its followers ranging between 1-1.8 billion globally, or around a quarter of the world's po ...

Architecture In Iran
Iranian architecture or Persian architecture (Persian: معمارى ایرانی, ''Memāri e Irāni'') is the architecture of Iran and parts of the rest of West Asia, the Caucasus and Central Asia. Its history dates back to at least 5,000 BC with characteristic examples distributed over a vast area from Turkey and Iraq to Uzbekistan and Tajikistan, and from the Caucasus to Zanzibar. Persian buildings vary from peasant huts to tea houses, and garden pavilions to "some of the most majestic structures the world has ever seen". In addition to historic gates, palaces, and mosques, the rapid growth of cities such as the capital Tehran has brought about a wave of demolition and new construction. Iranian architecture displays great variety, both structural and aesthetic, from a variety of traditions and experience. Without sudden innovations, and despite the repeated trauma of invasions and cultural shocks, it has achieved "an individuality distinct from that of other Muslim countries" ...

Latent Heat
Latent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition. Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature. Examples are latent heat of fusion and latent heat of vaporization involved in phase changes, i.e. a substance condensing or vaporizing at a specified temperature and pressure. The term was introduced around 1762 by Scottish chemist Joseph Black. It is derived from the Latin ''latere'' (''to lie hidden''). Black used the term in the context of calorimetry where a heat transfer caused a volume change in a body while its temperature was constant. In contrast to latent heat, sensible heat is energy transferred as heat, with a resultant temperature change in a body. Usage The terms ″sensible heat″ and ″l ...

Bernoulli's Principle
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. The principle is named after the Swiss mathematician and physicist Daniel Bernoulli, who published it in his book ''Hydrodynamica'' in 1738. Although Bernoulli deduced that pressure decreases when the flow speed increases, it was Leonhard Euler in 1752 who derived Bernoulli's equation in its usual form. The principle is only applicable for isentropic flows: when the effects of irreversible processes (like turbulence) and non-adiabatic processes (e.g. thermal radiation) are small and can be neglected. Bernoulli's principle can be applied to various types of fluid flow, resulting in various forms of Bernoulli's equation. The simple form of Bernoulli's equation is valid for incompressible flows (e.g. most liquid flows and gases moving at low Mach number). More advanced forms may be applied ...

Andaruni
Andaruni ( fa, اندرونی) in Iranian architecture, is the inner quarter where the women lived. It has been described as ''harem'' in Arabic. Private space In traditional Persian residential architecture the ''andaruni'' is a part of the house in which the private quarters are established. This is specifically where the women of the house are free to move about without being seen by an outsider (''na mahram''). This is also the place where women can interact with their kin ('' maharim'') without following the dress code or without wearing the '' hijab''. In case the patriarch of the house had more than one wife, each wife is given her own section in the ''andaruni'' as is the case for her mother-in-law or sister-in-law if they live with the family. The only men allowed in this area are those directly related to the lord of the house (his sons) and the lord himself, which may include boys under the age of puberty, and guests allowed in under special circumstances. The court ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harem
Harem ( Persian: حرمسرا ''haramsarā'', ar, حَرِيمٌ ''ḥarīm'', "a sacred inviolable place; harem; female members of the family") refers to domestic spaces that are reserved for the women of the house in a Muslim family. A harem may house a man's wife or wives, their pre-pubescent male children, unmarried daughters, female domestic servants, and other unmarried female relatives. In harems of the past, slave concubines were also housed in the harem. In former times some harems were guarded by eunuchs who were allowed inside. The structure of the harem and the extent of monogamy or polygamy has varied depending on the family's personalities, socio-economic status, and local customs. Similar institutions have been common in other Mediterranean and Middle Eastern civilizations, especially among royal and upper-class families, and the term is sometimes used in other contexts. In traditional Persian residential architecture the women's quarters were known as ''andar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
