Learn About Gothic Literature With Elements and Examples

Learn About Gothic Literature With Elements and Examples The term Gothic originates with the ornate architecture created by Germanic tribes called the Goths.  It was then later expanded to include most of the medieval style of architecture. The ornate and intricate style of this kind of architecture proved to be the ideal backdrop for both the physical and the psychological settings in a new literary style, one that concerned itself with elaborate tales of mystery, suspense, and superstition. The height of the Gothic period, which was closely aligned with Romanticism, is usually considered to have been the years 1764–1840, but its influence extends to the present day in authors such as V.C. Andrews. Plot and Examples The plot of Gothic literature novels typically involves people who become involved in complex and oftentimes evil paranormal schemes, usually against an innocent and helpless heroine. One such example is the young Emily St. Aubert in Anne Radcliffe’s classic Gothic novel, The Mysteries of Udolpho (1794). This novel would inspire parody in Jane Austen’s Northanger Abbey (1817). The most famous example of pure Gothic fiction is perhaps the first example of the genre, Horace Walpole’s The Castle of Otranto (1764). Although rather short, the setting certainly fits the description given above, and the combined elements of terror and medievalism set a precedent for an entirely new, thrilling genre. Selected Bibliography In addition to The Mysteries of Udolpho and The Castle of Otranto, there are a number of classic novels that those who are interested in Gothic literature will want to pick up. Here is a list of 10 titles that are not to be missed: The History of the Caliph Vathek (1786) by William Thomas BeckfordThe Monk (1796) by Mathew LewisFrankenstein (1818) by Mary ShelleyMelmoth the Wanderer (1820) by Charles MaturinSalathiel the Immortal (1828) by George CrolyThe Hunchback of Notre-Dame (1831) by Victor HugoThe Fall of the House of Usher (1839) by Edgar Allan PoeVarney the Vampire; or, the Feast of Blood (1847) by James Malcolm RymerThe Strange Case of Dr. Jekyll and Mr. Hyde (1886) by Robert Louis StevensonDracula (1897) by Bram Stoker Key Elements In most of the examples above, one will find certain key elements ascribed to Gothic fiction.  They  include: Atmosphere: In the Gothic novel, the atmosphere will be one of mystery, suspense, and fear, the mood of which is only enhanced by elements of the unknown or unexplained. Clergy: Often, as in The Monk and The Castle of Otranto, the clergy play important secondary roles. They are often weak and sometimes outrageously evil. The paranormal: Oftentimes Gothic fiction will contain elements of the supernatural or paranormal, such as ghosts and vampires. In some instances, these supernatural features are later explained in perfectly natural terms, but in other works, they remain completely inexplicable. Melodrama: Also called â€Å"high emotion,† melodrama is created through highly sentimental language and overly emotional characters. The panic, terror, and other emotions can seem overwrought in order to make the characters and setting seem wild and out of control. Omens: Typical of the genre, omens- or portents and visions- often foreshadow events to come. They can take many forms, such as dreams. Setting: The setting of a Gothic novel is typically a character in its own right. Gothic architecture plays an important role, so the stories are often set in a castle or large manor, which is typically abandoned. Other settings may include caves or the wilderness. Virginal maiden in distress: With the exception of a few novels, such as Sheridan Le Fanu’s Carmilla (1872), most Gothic villains are powerful males who prey on young, virginal women. This dynamic creates tension and appeals deeply to the readers pathos, particularly as these heroines tend to be orphaned, abandoned, or somehow severed from the world, without guardianship. Modern Critiques Modern readers and critics have begun to think of Gothic literature as referring to any story that uses an elaborate setting, combined with supernatural or super-evil forces against an innocent protagonist. The contemporary understanding is similar but has widened to include a variety of genres, such as paranormal and horror.

Why ETFE Is the Miracle Construction Material

Why ETFE Is the Miracle Construction Material ETFE is an abbreviation for Ethylene Tetrafluoroethylene, a  translucent polymer sheeting that is used instead of glass and hard plastic in some modern buildings. ETFE is usually installed within a metal framework, where each unit can be lighted and manipulated independently. Light sources can be on either side of the plastic cladding. Compared to glass, ETFE transmits more light, insulates better, and costs 24 to 70 percent less to install. ETFE is only 1/100 the weight of glass, and it has properties that make it more flexible as a construction material and a medium for dynamic illumination. Key Takeaways: ETFE ETFE (Ethylene Tetrafluoroethylene) is an industrial-strength construction plastic used for exterior cladding since the 1980s.ETFE is strong and lightweight. It is often applied in layers that are welded together around the edges and held by a metal framework. Because it is safer and more adaptable than glass, non-rip ETFE is often used as a replacement for glass.Commercial uses of ETFE include many sports arenas and entertainment venues. Dynamic lighting of this plastic has been a successful feature of ETFE architecture. Uses of ETFE The SSE Hydro in Scotland, part of the design portfolio of British architect Norman Foster, was completed in 2013 as an entertainment venue. In the daylight, the ETFE cladding may lack excitement but be functional by allowing natural light to the interiors. After dark, however, the building can become a light show, with interior lighting shining out or exterior lights around the frames, creating surface colors that can be changed with the flip of a computer program. For other venues, rows of lights surround the plastic panels. The ETFE cusions on the Allianz Arena in Germany are diamond shaped. Each cushion can be controlled digitally to display red, blue, or white lights - depending on which home team is playing. ETFE Exterior Panels on the Allianz Arena. Lennart Preiss/Getty Images This material has been called a fabric, a film, and a foil. It can be sewn, welded, and glued together. It can be used as a single, one-ply sheet or it can be layered, with multiple sheets. The space between the layers can be pressurized to regulate both insulating values and light transmission. Light can also be regulated for local climates by applying nontransmittable patterns (e.g., dots) during the manufacturing process. With dark dots imprinted on the translucent plastic, light rays are deflected. These application patterns can be used in conjunction with layering - using photo sensors and computer programs, the location of the dots can be strategically moved by controlling the air between layers, by stretching or sagging the material, which positions the dots to block where the sun is shining through.

When the exterior of the Allianz Arena is red, FC Bayern Munich is the home team playing in the stadium - their team colors are red and white. When the TSV 1860 Mà ¼nchen soccer team plays, the colors of the stadium change to blue and white - that teams colors. Characteristics of ETFE ETFE is often called a miracle construction material for tensile architecture. ETFE is (1) strong enough to bear 400 times its own weight; (2) thin and lightweight; (3) stretchable to three times its length without loss of elasticity; (4) repaired by welding patches of tape over tears; (5) nonstick with a surface that resists dirt and birds; (6) expected to last as long as 50 years. In addition, ETFE doesnt burn, although it can melt before it self-extinquishes. Because of its strength and ability to transmit UV rays from the sun, ETFE is frequently used in sports venues that desire healthy, natural turf athletic fields. Disadvantages of ETFE Everything about ETFE is not miraculous. For one thing, it is not a natural building material - its plastic, after all. Also, ETFE transmits more sound than glass, and can be too noisy for some places. For a roof subject to raindrops, the workaround is to add another layer of film, thus decreasing the deafening drumbeats of rain but increasing the construction price. ETFE is usually applied in several layers that must be inflated and require steady air pressure. Depending on how the architect has designed it, the look of a building could drastically change if the machines that supply the pressure fail. As a relatively new product, ETFE is used in large commercial ventures - working with ETFE is too complex for small residential projects, for the time being. The Full Life Cycle of Building Materials How is it that a synthetic plastic film has come to be known as the building material of sustainability? When choosing building products, consider the life cycle of the materials. For example, vinyl siding may be recycled after its usefulness, but what energy was used and how was the environment polluted by its original manufacturing process? Concrete recycling is also celebrated in the environmentally friendly construction world, but the manufacturing process is one of the prime contributers to greenhouse gasses. A basic ingredient in concrete is cement, and the U.S. Environmental Protection Agency (EPA) tells us that the manufacturing of cement is the third largest industrial source of pollution in the world. When thinking of the life cycle of glass production, especially compared to ETFE, consider the energy used to create it and the necessary packaging to transport the product. Amy Wilson is explainer-in-chief for Architen Landrell, one of the worlds leaders in tensile architecture and fabric systems. She tells us that manufacturing ETFE causes little damage to the ozone layer. The raw material associated with ETFE is a class II substance admitted under the Montreal treaty, Wilson writes. Unlike its class I counterparts it causes minimal damage to the ozone layer, as is the case for all materials used in the manufacturing process. Reportedly creating ETFE uses less energy than making glass. Wilson explains: The production of ETFE involves the transformation of the monomer TFE in to the polymer ETFE using polymerisation; no solvents are used in this water based procedure. The material is then extruded to varying thicknesses depending on application; a process which uses minimal energy. Fabrication of the foil involves welding large sheets of the ETFE; this is relatively quick and again a low energy consumer. Because ETFE is also recyclable, the environmental  culpability is not in the polymer, but in the aluminum frames that hold the plastic layers. The aluminium frames do require a high level of energy for production, Wilson writes, but they also have a long life and are readily recycled when they reach their end of life. Examples of ETFE Structures A photo journey of ETFE architecture quickly dispels the notion that this is a simple plastic cladding material you might put over your roof or boat on a rainy day. The Swiss architecture team of Jacques Herzog and Pierre de Meuron created a sculpted look for the Allianz Arena (2005), one of the most beautiful ETFE structures in Mà ¼nchen-Frà ¶ttmaning, Germany. Mangrove Hall (1982) at Royal Burgers Zoo in Arnhem, the Netherlands, is said to be the first application of ETFE cladding. The Water Cube venue (2008) built for the Beijing, China Olympics brought the material to the attention of the world. The biodome Eden Project (2000) in Cornwall, England created a green tinge to the synthetic material. Allianz Arena Designed by Herzog de Meuron, 2005, Munich, Bavaria, Germany. Chan Srithaweeporn/Getty Images (cropped) Because of its flexibility and portability, temporary structures such as the summer Serpentine Gallery Pavilions in London, England have been of late at least partially created with ETFE; the 2015 pavilion in particular looked like a colorful colon. The roofs of modern sports stadia, including the U.S. Bank Stadium (2016) in Minneapolis, Minnesota, are often ETFE - they look like panes of glass, but the material is really safe, non-rip plastic.

Lionel Derimais/Getty Images (cropped) Plastics, the Industrial Revolution Continues The du Pont family emigrated to America shortly after the French Revolution, bringing with them 19th century skills in making explosives. Using chemistry to develop synthetic products never stopped within the DuPont company, creators of nylon in 1935 and Tyvek in 1966. When Roy Plunkett worked at DuPont in the 1930s, his team accidentally invented PTFE (polytetrafluoroethylene), which became Teflon. ® The company, who considers themselves a pioneer of polymer science with a legacy of innovation, is said to have created ETFE in the 1970s as an insulation coating for the aerospace industry. The tensile architecture of Prizker laureate Frei Otto in the 1960s and 1970s was an inspiration for engineers to come up with the best material to use for what builders and architects call cladding, or the material that we might call exterior siding for our homes. The idea for ETFE as a film cladding came in the 1980s.  Engineer Stefan Lehnert and architect Ben Morris co-founded Vector Foiltec to create and market Texlon ® ETFE, a multi-layered system of ETFE sheets and architectural cladding. They didnt invent the material, but they did invent the process for welding together sheets of ETFE - and giving a building the layered look. Sources Birdair.
