Asymmetry Magazine
Asymmetry is the absence of, or a violation of, symmetry (the property of an object being invariant to a transformation, such as reflection). Symmetry is an important property of both physical and abstract systems and it may be displayed in precise terms or in more aesthetic terms. The absence of or violation of symmetry that are either expected or desired can have important consequences for a system. In organisms Due to how cells divide in organisms, asymmetry in organisms is fairly usual in at least one dimension, with biological symmetry also being common in at least one dimension. Louis Pasteur proposed that biological molecules are asymmetric because the cosmic .e. physicalforces that preside over their formation are themselves asymmetric. While at his time, and even now, the symmetry of physical processes are highlighted, it is known that there are fundamental physical asymmetries, starting with time. Asymmetry in biology Asymmetry is an important and widespread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birth Defect
A birth defect, also known as a congenital disorder, is an abnormal condition that is present at birth regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional disorders in which problems exist with how a body part works. Functional disorders include metabolic and degenerative disorders. Some birth defects include both structural and functional disorders. Birth defects may result from genetic or chromosomal disorders, exposure to certain medications or chemicals, or certain infections during pregnancy. Risk factors include folate deficiency, drinking alcohol or smoking during pregnancy, poorly controlled diabetes, and a mother over the age of 35 years old. Many are believed to involve multiple factors. Birth defects may be visi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Fire Protection
Passive fire protection (PFP) is components or systems of a building or structure that slows or impedes the spread of the effects of fire or smoke without system activation, and usually without movement. Examples of passive systems include floor-ceilings and roofs, fire doors, windows, and wall assemblies, fire-resistant coatings, and other fire and smoke control assemblies. Passive fire protection systems can include active components such as fire dampers. Main characteristics Passive fire protection systems are intended to: * Contain a fire to the compartment of fire origin * Slow a fire from spreading from the compartment of fire origin * Slow the heating of structural members * Prevent the spread of fire through intentional openings (e.g., doors, HVAC ducts) in fire rated assemblies by the use of a fire rated closure (e.g., fire door, fire damper) * Prevent the spread of fire through penetrations (e.g., holes in fire walls through which building systems such as plumbing ...

Fire-resistance Rating
A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail other criteria, involving evidence of functionality or fitness for purpose. Common rating systems The following depict the most commonly used international time/temperature curves: File:Din iso astm ul curves.JPG, Time/Temperature Curves used for testing the fire-resistance rating of passive fire protection systems such as firestops, fire doors, wall and floor assemblies, etc., which are used in compartmentalisation in buildings and the petrochemical industry in Europe and North America.

Outrigger Canoe
Outrigger boats are various watercraft featuring one or more lateral support floats known as outriggers, which are fastened to one or both sides of the main hull. They can range from small dugout canoes to large plank-built vessels. Outrigger boats can also vary in their configuration, from the ancestral double-hull configuration (catamarans), to single-outrigger vessels prevalent in the Pacific Islands and Madagascar, to the double-outrigger vessels (trimarans) prevalent in Island Southeast Asia. They are traditionally fitted with Austronesian sails, like the crab claw sails and tanja sails, but in modern times are often fitted with petrol engines. Unlike a single-hulled vessel, an outrigger or double-hull vessel generates stability as a result of the distance between its hulls rather than due to the shape of each individual hull. As such, the hulls of outrigger or double-hull boats are typically longer, narrower and more hydrodynamically efficient than those of single-hul ...

Proa
Proas are various types of multi-hull outrigger sailboats of the Austronesian peoples. The terms were used for native Austronesian ships in European records during the Colonial era indiscriminately, and thus can confusingly refer to the double-ended single-outrigger boats of Oceania, the double-outrigger boats of Island Southeast Asia, and sometimes ships with no outriggers or sails at all. In its most common usage, the term ''proa'' refers to the Pacific proas which consist of two (usually) unequal-length parallel hulls. It is sailed so that one hull is kept to windward, and the other to leeward. It is double-ended, since it needs to " shunt" to reverse direction when tacking. It is most famously used for the ''sakman'' ships of the Chamorro people of the Northern Marianas, which were known as the "flying proas" for their remarkable speed. In Island Southeast Asia, the term ''proa'' may also sometimes be used, but the terms perahu, prau, prahu, paraw and prow are more ...

Blohm & Voss BV 141
The Blohm & Voss BV 141 was a World War II German tactical reconnaissance aircraft, notable for its uncommon structural asymmetry. Although the Blohm & Voss BV 141 performed well, it was never ordered into full-scale production, for reasons that included the unavailability of the preferred engine and competition from another tactical reconnaissance aircraft, the Focke-Wulf Fw 189. Development In 1937, the German Air Ministry – the ''Reichsluftfahrtministerium'' (RLM) – issued a specification for a single-engine reconnaissance aircraft with optimal visual characteristics. The preferred contractor was Arado with the Ar 198, but the prototype proved unsuccessful.. The eventual winner was the Focke-Wulf Fw 189 ''Uhu''; even though its twin-boom design using two smaller engines did not match the requirement of a single engined aircraft. Blohm & Voss ( Hamburger Flugzeugbau) although not invited to participate, pursued as a private venture something far more radical. The proposa ...

Auditorio De Tenerife
The Auditorio de Tenerife "Adán Martín" (commonly referred to as the Auditorio de Tenerife) is an auditorium in Santa Cruz de Tenerife, Canary Islands, Spain. Designed by architect Santiago Calatrava, it is located on the Avenue of the Constitution in the Canarian capital, and next to the Atlantic Ocean in the southern part of Port of Santa Cruz de Tenerife. Construction began in 1997 and was completed in 2003. The auditorium was inaugurated on 26 September of that year in the presence of Felipe, Prince of Asturias, and was later visited by former U.S. President Bill Clinton. The building is framed within the tenets of late-modern architecture of the late 20th century. The majestic profile of the auditorium has become an architectural symbol of the city of Santa Cruz de Tenerife, the island of Tenerife and the Canary Islands. It is also regarded as the finest contemporary building in the Canary Islands and one of the most emblematic buildings of Spanish architecture. In March 20 ...

Puente De La Mujer
The Puente de la Mujer (Spanish for "Woman's Bridge") is a rotating footbridge for Dock 3 of the Puerto Madero commercial district of Buenos Aires, Argentina. It is of the cantilever spar cable-stayed bridge type and is also a swing bridge, but somewhat unusual in its asymmetrical arrangement. It has a single mast with cables suspending a portion of the bridge which rotates 90 degrees in order to allow water traffic to pass. When it swings to allow watercraft passage, the far end comes to a resting point on a stabilizing pylon. History Designed by the Spanish architect and structural engineer Santiago Calatrava on a plan very similar to a 251-metre bridge over the Guadalquivir River in Seville, Spain (1992) and a 213-metre bridge over the Sacramento River in Redding, California (2004), it has a forward-, rather than a reverse-angled cantilever, as is seen in those bridges. Started in 1998, it was inaugurated on December 20, 2001, and is the first of only two Calatrava structures in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Postmodernism
Postmodernism is an intellectual stance or Rhetorical modes, mode of discourseNuyen, A.T., 1992. The Role of Rhetorical Devices in Postmodernist Discourse. Philosophy & Rhetoric, pp.183–194. characterized by philosophical skepticism, skepticism toward the "meta-narrative, grand narratives" of modernism, opposition to epistemological, epistemic certainty or stability of meaning (semiotics), meaning, and emphasis on ideology as a means of maintaining political power. Claims to objective fact are dismissed as naïve realism, with attention drawn to the instrumental conditionality, conditional nature of knowledge claims within particular historical, political, and cultural discourses. The postmodern outlook is characterized by self-reference, self-referentiality, epistemological relativism, moral relativism, pluralism (philosophy), pluralism, irony, irreverence, and eclecticism; it rejects the "universal validity" of binary oppositions, stable identity (philosophy), identity, hierar ...

Modern Architecture
Modern architecture, or modernist architecture, was an architectural movement or architectural style based upon new and innovative technologies of construction, particularly the use of glass, steel, and reinforced concrete; the idea that form should follow function ( functionalism); an embrace of minimalism; and a rejection of ornament. It emerged in the first half of the 20th century and became dominant after World War II until the 1980s, when it was gradually replaced as the principal style for institutional and corporate buildings by postmodern architecture.
