Front de Seine. Front de Seine is a development in the district of Beaugrenelle in Paris, France, located along the river Seine in the 15th arrondissement at the south of the Eiffel Tower. It is, with the 13th arrondissement, one of the few districts in the city of Paris containing highrise buildings, as most have been constructed outside the city (notably in La Défense).The Front de Seine district is the result of an urban planning project from the 1970s. It includes about 20 towers reaching nearly 100 m of height built all around an elevated esplanade. That esplanade is paved with frescos that.

Front de Seine. can be seen only from the elevated floors of the towers. As opposed to Italie 13, the design of the towers is much more varied. The Hôtel Novotel Paris-Tour Eiffel (formerly known as Hôtel Nikkō), for instance, has red-encircled windows, while the Tour Totem consists of a stack of several glazed blocks.A newly redesigned shopping centre, the Centre commercial Beaugrenelle opened in 2013.Furthermore, while 13th arrondissement towers are predominantly residential and La Défense towers are predominantly commercial, the towers of the Front de Seine are of mixed commercial and residential use.

Battersea Power Station. Irish company Real Estate Opportunities (REO), who bought it for £400 million in November 2006 with plans to refurbish the station for public use and build 3,400 homes on the site. This plan fell through due to REO's debt being called in by the state-owned banks of the UK and Ireland. The site was again put up for sale in December 2011 through commercial estate agent Knight Frank. The combination of an existing debt burden of some £750 million, the need to make a £200 million contribution to an extension to the London Underground, requirements to fund conservation of the.

It was nearly identical to the A Station from the outside and was constructed directly to its east as a mirror to it, which gave the power station its now familiar four-chimney layout. The construction of the B Station brought the site's generating capacity up to 509 megawatts (MW), making it the third largest generating site in the UK at the time, providing a fifth of London's electricity needs (with the remainder supplied by 28 smaller.

It was also the most thermally efficient power station in the world when it opened.The A Station had been operated by the London Power Company, but by the time the B Station was completed, the UK's electric supply industry had been nationalised, and ownership of the two stations had passed into the hands of the British Electricity Authority in 1948.On 20 April 1964, the power station was the site of a fire that caused power failures throughout London, including at the BBC Television Centre, which was due to launch BBC2 that night. The launch was delayed until the following.

The station was designed in the "brick-cathedral" style of power station design, which was popular at the time. Battersea is one of a very small number of examples of this style of power station design still in existence in the UK, others being Uskmouth and Bankside. The station's design proved popular straightaway, and was described as a "temple of power", which ranked equal with St Paul's Cathedral as a London landmark. In a.

Combined, these gave the B station a generating capacity of 260 MW, making the site's generating capacity 503 MW. All of the station's boilers were made by Babcock & Wilcox, fuelled by pulverised coal from pulverisers also built by Babcock & Wilcox. There were nine boilers in the A station and six in the B station. The B station's boilers were the largest ever built in the UK at that time. The B station also had the highest.

Beaver. Prior to that, many considered them the same species. The difference in chromosome numbers prevents them from interbreeding. 25 subspecies have been classified for "C. canadensis" and nine for "C. fiber".## Evolution.Beavers belong to the rodent suborder Castorimorpha, along with Heteromyidae (kangaroo rats and kangaroo mice), and the gophers. Modern beavers are the only extant members of the family Castoridae. They originated in North America in the late Eocene and colonized Eurasia via the Bering Land Bridge in the early Oligocene, coinciding with the "Grande Coupure", a time of significent changes in animal species around 33million years ago (mya).The more.

Fresnel lens. A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships."The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens.

Fresnel lens. was first proposed by Count Buffon and independently reinvented by Fresnel. The "catadioptric" form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.## Description.The Fresnel lens reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections. An ideal Fresnel lens would have an infinite number of sections. In each section, the overall.

Fresnel lens. thickness is decreased compared to an equivalent simple lens. This effectively divides the continuous surface of a standard lens into a set of surfaces of the same curvature, with stepwise discontinuities between them.In some lenses, the curved surfaces are replaced with flat surfaces, with a different angle in each section. Such a lens can be regarded as an array of prisms arranged in a circular fashion with steeper prisms on the edges and a flat or slightly convex center. In the first (and largest) Fresnel lenses, each section was actually a separate prism. 'Single-piece' Fresnel lenses were later produced, being.

Fresnel lens. used for automobile headlamps, brake, parking, and turn signal lenses, and so on. In modern times, computer-controlled milling equipment (CNC) or 3-D printers might be used to manufacture more complex lenses.Fresnel lens design allows a substantial reduction in thickness (and thus mass and volume of material) at the expense of reducing the imaging quality of the lens, which is why precise imaging applications such as photography usually still use larger conventional lenses.Fresnel lenses are usually made of glass or plastic; their size varies from large (old historical lighthouses, meter size) to medium (book-reading aids, OHP viewgraph projectors) to small (TLR/SLR.

Fresnel lens. camera screens, micro-optics). In many cases they are very thin and flat, almost flexible, with thicknesses in the 1 to 5 (mm) range.Most modern Fresnel lenses consist only of refractive elements. Lighthouse lenses, however, tend to include both refracting and reflecting elements, the latter being "outside" the metal rings seen in the photographs. While the inner elements are sections of refractive lenses, the outer elements are reflecting prisms, each of which performs two refractions and one total internal reflection, avoiding the light loss that occurs in reflection from a silvered mirror.## Lighthouse lens sizes.Fresnel designed six sizes of lighthouse lenses,.

Fresnel lens. divided into four "orders" based on their size and focal length. In modern use, these are classified as first through sixth order. An intermediate size between third and fourth order was added later, as well as sizes above first order and below sixth.A first-order lens has a focal length of 920 (mm) and stands about 2.59 (m) high, and 1.8 (m) wide. The smallest (sixth) order has a focal length of 150 (mm) and a height of 433 (mm).The largest Fresnel lenses are called hyperradiant (or hyper-radial). One such lens was on hand when it was decided to build and.

Fresnel lens. outfit the Makapuu Point Light in Hawaii. Rather than order a new lens, the huge optic construction, 12 (ft) tall and with over a thousand prisms, was used there.## Types.There are two main types of Fresnel lens: "imaging" and "non-imaging". Imaging Fresnel lenses use segments with curved cross-sections and produce sharp images, while non-imaging lenses have segments with flat cross-sections, and do not produce sharp images. As the number of segments increases, the two types of lens become more similar to each other. In the abstract case of an infinite number of segments, the difference between curved and flat segments.

Fresnel lens. disappears.Spherical: A spherical Fresnel lens is equivalent to a simple spherical lens, using ring-shaped segments that are each a portion of a sphere, that all focus light on a single point. This type of lens produces a sharp image, although not quite as clear as the equivalent simple spherical lens due to diffraction at the edges of the ridges.Cylindrical: A cylindrical Fresnel lens is equivalent to a simple cylindrical lens, using straight segments with circular cross-section, focusing light on a single line. This type produces a sharp image, although not quite as clear as the equivalent simple cylindrical lens due.

Fresnel lens. to diffraction at the edges of the ridges.Spot: A non-imaging spot Fresnel lens uses ring-shaped segments with cross sections that are straight lines rather than circular arcs. Such a lens can focus light on a small spot, but does not produce a sharp image. These lenses have application in solar power, such as focusing sunlight on a solar panel. Fresnel lenses may be used as components of Köhler illumination optics resulting in very effective nonimaging optics Fresnel-Köhler (FK) solar concentrators.Linear: A non-imaging linear Fresnel lens uses straight segments whose cross sections are straight lines rather than arcs. These lenses focus.

Fresnel lens. light into a narrow band. They do not produce a sharp image, but can be used in solar power, such as for focusing sunlight on a pipe, to heat the water within.## Uses.## Imaging.Fresnel lenses are used as simple hand-held magnifiers. They are also used to correct several visual disorders, including ocular-motility disorders such as strabismus. Fresnel lenses have been used to increase the visual size of CRT displays in pocket televisions, notably the Sinclair TV80. They are also used in traffic lights.Fresnel lenses are used in left-hand-drive European lorries entering the UK and Republic of Ireland (and vice versa,.

Fresnel lens. right-hand-drive Irish and British trucks entering mainland Europe) to overcome the blind spots caused by the driver operating the lorry while sitting on the wrong side of the cab relative to the side of the road the car is on. They attach to the passenger-side window.Another automobile application of a Fresnel lens is a rear view enhancer, as the wide view angle of a lens attached to the rear window permits examining the scene behind a vehicle, particularly a tall or bluff-tailed one, more effectively than a rear-view mirror alone.Multi-focal Fresnel lenses are also used as a part of retina.

Fresnel lens. identification cameras, where they provide multiple in- and out-of-focus images of a fixation target inside the camera. For virtually all users, at least one of the images will be in focus, thus allowing correct eye alignment.Fresnel lenses have also been used in the field of popular entertainment. The British rock artist Peter Gabriel made use of them in his early solo live performances to magnify the size of his head, in contrast to the rest of his body, for dramatic and comic effect. In the Terry Gilliam film "Brazil", plastic Fresnel screens appear ostensibly as magnifiers for the small CRT.

Fresnel lens. monitors used throughout the offices of the Ministry of Information. However, they occasionally appear between the actors and the camera, distorting the scale and composition of the scene to humorous effect. The Pixar movie Wall-E features a Fresnel lens in the scenes where the protagonist watches the musical Hello, Dolly! magnified on an iPod.## Photography.Canon and Nikon have used Fresnel lenses to reduce the size of telephoto lenses. Photographic lenses that include Fresnel elements can be much shorter than corresponding conventional lens design. Nikon calls the technology "Phase Fresnel".The Polaroid SX-70 camera used a Fresnel reflector as part of its.

Fresnel lens. viewing system.View and large format cameras can utilize a Fresnel lens in conjunction with the ground glass, to increase the perceived brightness of the image projected by a lens onto the ground glass, thus aiding in adjusting focus and composition.## Illumination.High-quality glass Fresnel lenses were used in lighthouses, where they were considered state of the art in the late 19th and through the middle of the 20th centuries; most lighthouses have now retired glass Fresnel lenses from service and replaced them with much less expensive and more durable aerobeacons, which themselves often contain plastic Fresnel lenses. Lighthouse Fresnel lens systems.

Fresnel lens. typically include extra annular prismatic elements, arrayed in faceted domes above and below the central planar Fresnel, in order to catch all light emitted from the light source. The light path through these elements can include an internal reflection, rather than the simple refraction in the planar Fresnel element. These lenses conferred many practical benefits upon the designers, builders, and users of lighthouses and their illumination. Among other things, smaller lenses could fit into more compact spaces. Greater light transmission over longer distances, and varied patterns, made it possible to triangulate a position.Perhaps the most widespread use of Fresnel lenses,.

Fresnel lens. for a time, occurred in automobile headlamps, where they can shape the roughly parallel beam from the parabolic reflector to meet requirements for dipped and main-beam patterns, often both in the same headlamp unit (such as the European H4 design). For reasons of economy, weight, and impact resistance, newer cars have dispensed with glass Fresnel lenses, using multifaceted reflectors with plain polycarbonate lenses. However, Fresnel lenses continue in wide use in automobile tail, marker, and reversing lights.Glass Fresnel lenses also are used in lighting instruments for theatre and motion pictures (see Fresnel lantern); such instruments are often called simply "Fresnels".

Fresnel lens. The entire instrument consists of a metal housing, a reflector, a lamp assembly, and a Fresnel lens. Many Fresnel instruments allow the lamp to be moved relative to the lens' focal point, to increase or decrease the size of the light beam. As a result, they are very flexible, and can often produce a beam as narrow as 7° or as wide as 70°. The Fresnel lens produces a very soft-edged beam, so is often used as a wash light. A holder in front of the lens can hold a colored plastic film ("gel") to tint the light or wire.

Fresnel lens. screens or frosted plastic to diffuse it. The Fresnel lens is useful in the making of motion pictures not only because of its ability to focus the beam brighter than a typical lens, but also because the light is a relatively consistent intensity across the entire width of the beam of light.Aircraft carriers and naval air stations typically use Fresnel lenses in their optical landing systems. The "meatball" light aids the pilot in maintaining proper glide slope for the landing. In the center are amber and red lights composed of Fresnel lenses. Although the lights are always on, the angle.

Fresnel lens. of the lens from the pilot's point of view determines the color and position of the visible light. If the lights appear above the green horizontal bar, the pilot is too high. If it is below, the pilot is too low, and if the lights are red, the pilot is very low.Fresnel lenses are also commonly used in searchlights, spotlights, and flashlights.## Projection.The use of Fresnel lenses for image projection reduces image quality, so they tend to occur only where quality is not critical or where the bulk of a solid lens would be prohibitive. Cheap Fresnel lenses can be.

Fresnel lens. stamped or molded of transparent plastic and are used in overhead projectors and projection televisions.Fresnel lenses of different focal lengths (one collimator, and one collector) are used in commercial and DIY projection. The collimator lens has the lower focal length and is placed closer to the light source, and the collector lens, which focuses the light into the triplet lens, is placed after the projection image (an active matrix LCD panel in LCD projectors). Fresnel lenses are also used as collimators in overhead projectors.## Solar power.Since plastic Fresnel lenses can be made larger than glass lenses, as well as being.

Fresnel lens. much cheaper and lighter, they are used to concentrate sunlight for heating in solar cookers, in solar forges, and in solar collectors used to heat water for domestic use. They can also be used to generate steam or to power a Stirling engine.Fresnel lenses can concentrate sunlight onto solar cells with a ratio of almost 500:1. This allows the active solar-cell surface to be reduced, lowering cost and allowing the use of more efficient cells that would otherwise be too expensive. In the early 21st century, Fresnel reflectors began to be used in concentrating solar power (CSP) plants to concentrate.

Fresnel lens. solar energy. One application was to preheat water at the coal-fired Liddell Power Station, in Hunter Valley Australia.Fresnel lenses can be used to sinter sand, allowing 3D printing in glass.## History.## Forerunners.Augustin-Jean Fresnel was not the first person to focus a lighthouse beam using a lens. That distinction apparently belongs to the London glass-cutter Thomas Rogers, who proposed the idea to Trinity House in 1788. The first Rogers lenses, 53cm in diameter and 14cm thick at the center, were installed at the Old Lower Lighthouse at Portland Bill in 1789. Behind each lamp was a back-coated spherical glass mirror, which.

Fresnel lens. reflected rear radiation back through the lamp and into the lens. Further samples were installed at Howth Baily, North Foreland, and at least four other locations by 1804. But much of the light was wasted by absorption in the glass.Nor was Fresnel the first to suggest replacing a convex lens with a series of concentric annular prisms, to reduce weight and absorption. In 1748, Count Buffon proposed grinding such prisms as steps in a single piece of glass. In 1790 (although secondary sources give the date as 1773 or 1788), the Marquis de Condorcet suggested that it would be easier.

Fresnel lens. to make the annular sections separately and assemble them on a frame; but even that was impractical at the time. These designs were intended not for lighthouses, but for burning glasses. David Brewster, however, proposed a system similar to Condorcet's in 1811, and by 1820 was advocating its use in British lighthouses.## Fresnel's contributions.The French (Commission of Lighthouses) was established by Napoleon in 1811, and placed under the authority of Fresnel's employer, the Corps of Bridges and Roads. As the members of the commission were otherwise occupied, it achieved little in its early years. But on 21 June 1819—three months.

Fresnel lens. after winning the physics of the Academy of Sciences for his celebrated memoir on diffraction—Fresnel was "temporarily" seconded to the commission on the recommendation of François Arago (a member since 1813), to review possible improvements in lighthouse illumination.By the end of August 1819, unaware of the Buffon-Condorcet-Brewster proposal, Fresnel made his first presentation to the commission, recommending what he called ('lenses by steps') to replace the reflectors then in use, which reflected only about half of the incident light. Much to Fresnel's embarrassment, one of the assembled commissioners, Jacques Charles, recalled Buffon's suggestion. However, whereas Buffon's version was biconvex and.

Fresnel lens. in one piece, Fresnel's was plano-convex and made of multiple prisms for easier construction. With an official budget of 500 francs, Fresnel approached three manufacturers. The third, François Soleil, found a way to remove defects by reheating and remolding the glass. Arago assisted Fresnel with the design of a modified Argand lamp with concentric wicks (a concept that Fresnel attributed to Count Rumford), and accidentally discovered that fish glue was heat-resistant, making it suitable for use in the lens. The prototype, finished in March 1820, had a square lens panel 55cm on a side, containing 97 polygonal (not annular) prisms—and.

Fresnel lens. so impressed the Commission that Fresnel was asked for a full eight-panel version. This model, completed a year later in spite of insufficient funding, had panels 76cm square. In a public spectacle on the evening of 13 April 1821, it was demonstrated by comparison with the most recent reflectors, which it suddenly rendered obsolete.Soon after this demonstration, Fresnel published the idea that light, including apparently unpolarized light, consists exclusively of transverse waves, and went on to consider the implications for double refraction and partial reflection.Fresnel acknowledged the British lenses and Buffon's invention in a memoir read on 29 July 1822.

Fresnel lens. and printed in the same year. The date of that memoir may be the source of the claim that Fresnel's lighthouse advocacy began two years later than Brewster's; but the text makes it clear that Fresnel's involvement began no later than 1819.Fresnel's next lens was a rotating apparatus with eight "bull's-eye" panels, made in annular arcs by Saint-Gobain, giving eight rotating beams—to be seen by mariners as a periodic flash. Above and behind each main panel was a smaller, sloping bull's-eye panel of trapezoidal outline with trapezoidal elements. This refracted the light to a sloping plane mirror, which then reflected.

Fresnel lens. it horizontally, 7 degrees ahead of the main beam, increasing the duration of the flash. Below the main panels were 128 small mirrors arranged in four rings, stacked like the slats of a louver or Venetian blind. Each ring, shaped like a frustum of a cone, reflected the light to the horizon, giving a fainter steady light between the flashes. The official test, conducted on the unfinished on 20 August 1822, was witnessed by the Commission—and by Louis XVIII and his entourage—from 20 (mi) away. The apparatus was stored at Bordeaux for the winter, and then reassembled at Cordouan Lighthouse.

Fresnel lens. under Fresnel's supervision—in part by Fresnel's own hands. On 25 July 1823, the world's first lighthouse Fresnel lens was lit. As expected, the light was visible to the horizon, more than 20 (mi) out.The day before the test of the Cordouan lens in Paris, a committee of the Academy of Sciences reported on Fresnel's memoir and supplements on double refraction—which, although less well known to modern readers than his earlier work on diffraction, struck a more decisive blow for the wave theory of light. Between the test and the reassembly at Cordouan, Fresnel submitted his papers on photoelasticity (16 September.

Fresnel lens. 1822), elliptical and circular polarization and optical rotation (9 December), and partial reflection and total internal reflection (7 January 1823), essentially completing his reconstruction of physical optics on the transverse wave hypothesis. Shortly after the Cordouan lens was lit, Fresnel started coughing up blood.In May 1824, Fresnel was promoted to Secretary of the , becoming the first member of that body to draw a salary, albeit in the concurrent role of Engineer-in-Chief. Late that year, being increasingly ill, he curtailed his fundamental research and resigned his seasonal job as an examiner at the , in order to save his remaining.

Fresnel lens. time and energy for his lighthouse work.In the same year he designed the first "fixed" lens—for spreading light evenly around the horizon while minimizing waste above or below. Ideally the curved refracting surfaces would be segments of toroids about a common vertical axis, so that the dioptric panel would look like a cylindrical drum. If this was supplemented by reflecting (catoptric) rings above and below the refracting (dioptric) parts, the entire apparatus would look like a beehive. The second Fresnel lens to enter service was indeed a fixed lens, of third order, installed at Dunkirk by 1 February 1825. However,.

Fresnel lens. due to the difficulty of fabricating large toroidal prisms, this apparatus had a 16-sided polygonal plan.In 1825 Fresnel extended his fixed-lens design by adding a rotating array outside the fixed array. Each panel of the rotating array was to refract part of the fixed light from a horizontal fan into a narrow beam.Also in 1825, Fresnel unveiled the ('lighthouse map'), calling for a system of 51 lighthouses plus smaller harbor lights, in a hierarchy of lens sizes called "orders" (the first being the largest), with different characteristics to facilitate recognition: a constant light (from a fixed lens), one flash per.

Fresnel lens. minute (from a rotating lens with eight panels), and two per minute (16 panels).In late 1825, to reduce the loss of light in the reflecting elements, Fresnel proposed to replace each mirror with a catadioptric prism, through which the light would travel by refraction through the first surface, then total internal reflection off the second surface, then refraction through the third surface. The result was the lighthouse lens as we now know it. In 1826 he assembled a small model for use on the , but he did not live to see a full-sized version: he died on 14 July.

Fresnel lens. 1827, at the age of 39.## After Fresnel.The first stage of the development of lighthouse lenses after the death of Augustin Fresnel consisted in the implementation of his designs. This was driven in part by his younger brother Léonor—who, like Augustin, was trained as a civil engineer but, unlike Augustin, had a strong aptitude for management. Léonor entered the service of the Lighthouse Commission in 1825, and went on to succeed Augustin as Secretary.The first fixed lens to be constructed with toroidal prisms was a first-order apparatus designed by the Scottish engineer Alan Stevenson under the guidance of Léonor Fresnel,.

Fresnel lens. and fabricated by Isaac Cookson & Co. using French glass; it entered service at the Isle of May, Scotland, on 22 September 1836. The first large catadioptric lenses were made in 1842 for the lighthouses at Gravelines and Île Vierge, France; these were fixed third-order lenses whose catadioptric rings (made in segments) were one metre in diameter. Stevenson's first-order Skerryvore lens, lit in 1844, was only partly catadioptric; it was similar to the Cordouan lens except that the lower slats were replaced by French-made catadioptric prisms, while mirrors were retained at the top. The first "fully" catadioptric first-order lens, installed.

Fresnel lens. at Pointe d'Ailly in 1852, also gave eight rotating beams plus a fixed light at the bottom; but its top section had eight catadioptric panels focusing the light about 4 degrees ahead of the main beams, in order to lengthen the flashes. The first fully catadioptric lens with "purely revolving" beams—also of first order—was installed at Saint-Clément-des-Baleines in 1854, and marked the completion of Augustin Fresnel's original "Carte des Phares".Thomas Stevenson (younger brother of Alan) went a step beyond Fresnel with his "holophotal" lens, which focused the light radiated by the lamp in nearly all directions, forward or backward, into.

Fresnel lens. a single beam. The first version, described in 1849, consisted of a standard Fresnel bull's-eye lens, a paraboloidal reflector, and a rear hemispherical reflector (functionally equivalent to the Rogers mirror of 60 years earlier, except that it subtended a whole hemisphere). Light radiated into the forward hemisphere but missing the bull's-eye lens was deflected by the paraboloid into a parallel beam surrounding the bull's-eye lens, while light radiated into the backward hemisphere was reflected back through the lamp by the spherical reflector (as in Rogers' arrangement), to be collected by the forward components. The first unit was installed at North.

Fresnel lens. Harbour, Peterhead, in August 1849. Stevenson called this version a "catadioptric holophote", although each of its elements was either purely reflective or purely refractive. In the second version of the holophote concept, the bull's-eye lens and paraboloidal reflector were replaced by a catadioptric Fresnel lens—as conceived by Fresnel, but expanded to cover the whole forward hemisphere. The third version, which Stevenson confusingly called a "dioptric holophote", was more innovative: it retained the catadioptric Fresnel lens for the front hemisphere, but replaced the rear hemispherical reflector with a hemispherical array of annular prisms, each of which used "two" total internal reflections.

Fresnel lens. to turn light diverging from the center of the hemisphere back toward the center. The result was an all-glass holophote, with no losses from metallic reflections.James Timmins Chance modified Thomas Stevenson's all-glass holophotal design by arranging the double-reflecting prisms about a vertical axis. The prototype was shown at the 1862 International Exhibition in London. Later, to ease manufacturing, Chance divided the prisms into segments, and arranged them in a cylindrical form while retaining the property of reflecting light from a single point back to that point. Reflectors of this form, paradoxically called "dioptric mirrors", proved particularly useful for returning light.

Fresnel lens. from the landward side of the lamp to the seaward side.As lighthouses proliferated, they became harder to distinguish from each other, leading to the use of colored filters, which wasted light. In 1884, John Hopkinson eliminated the need for filters by inventing the "group-flashing" lens, in which the dioptric and/or the catadioptric panels were split so as to give multiple flashes—allowing lighthouses to be identified not only by frequency of flashes, but also by multiplicity of flashes. Double-flashing lenses were installed at Tampico (Mexico) and Little Basses (Sri Lanka) in 1875, and a triple-flashing lens at Casquets Lighthouse (Channel Islands).

Fresnel lens. in 1876. The example shown (right) is the double-flashing lens of the Point Arena Light, which was in service from 1908 to 1977.The development of hyper-radial lenses was driven in part by the need for larger light sources, such as gas lights with multiple jets, which required a longer focal length for a given beam-width, hence a larger lens to collect a given fraction of the generated light. The first hyper-radial lens was built for the Stevensons in 1885 by F. Barbier & Cie of France, and tested at South Foreland Lighthouse with various light sources. Chance Brothers (Hopkinson's employers).

Fresnel lens. then began constructing hyper-radials, installing their first at Bishop Rock Lighthouse in 1887. In the same year, Barbier installed a hyper-radial at Tory Island. But only about 30 hyper-radials went into service before the development of more compact bright lamps rendered such large optics unnecessary (see "Hyperradiant Fresnel lens").Production of one-piece stepped dioptric lenses—roughly as envisaged by Buffon—became feasible in 1852, when John L. Gilliland of the Brooklyn Flint-Glass Company patented a method of making lenses from pressed and molded glass. The company made small bull's-eye lenses for use on railroads, steamboats, and docks; such lenses were common in the.

Fresnel lens. United States by the 1870s. In 1858 the company produced "a very small number of pressed flint-glass sixth-order lenses" for use in lighthouses—the first Fresnel lighthouse lenses made in America. By the 1950s, the substitution of plastic for glass made it economic to use Fresnel lenses as condensers in overhead projectors.

Predjama Castle. Predjama Castle ( or , German: "", ) is a Renaissance castle built within a cave mouth in south-central Slovenia, in the historical region of Inner Carniola. It is located in the village of Predjama, approximately 11 kilometres from the town of Postojna and 9 kilometres from Postojna Cave.## History of the castle.The castle was first mentioned in 1274 with the German name "Luegg", when the Patriarch of Aquileia built the castle in Gothic style. The castle was built under a natural rocky arch high in the stone wall to make access to it difficult. It was later acquired and.

Predjama Castle. expanded by the Luegg noble family, also known as the Knights of Adelsberg (the German name of Postojna).## Legend of Erasmus of Lueg.The castle became known as the seat of the knight Erasmus of Lueg (or Luegg, Luegger), lord of the castle in the 15th century and a renowned robber baron. He was the son of the imperial governor of Trieste, Nikolaj Lueger.According to legend, Erasmus came into conflict with the Habsburgs when he killed the commander of the imperial army, Marshal Pappenheim, who had offended the honour of Erasmus's deceased friend and famous condottiere Andrej Baumkircher of Vipava. Fleeing.

From there, he allied himself with King Matthias Corvinus and began to attack Habsburg estates and towns in Carniola. The emperor commissioned the governor of Trieste, Andrej Ravbar, with the capture or killing of Erasmus. Erasmus was killed after a long siege. According to a popular but unfounded legend, Erasmus was betrayed by one of his men and was killed by a shot from a cannon in his lavatory.## After the reconstruction.After the siege and destruction of the original castle, its ruins were acquired.

Predjama Castle. by the Oberburg family. In 1511, the second castle, built by the Purgstall family in the first decade of the 16th century, was destroyed in an earthquake. In the year 1567, Archduke Charles of Austria leased the castle to Baron Philipp von Cobenzl, who paid it off after 20 years. In 1570, the current castle was built in the Renaissance style, pressed next to a vertical cliff under the original medieval fortification. The castle has remained in this form, virtually unchanged, to the present day.In the 18th century, it became one of the favourite summer residences of the Cobenzl family.

Predjama Castle. Both the Austrian statesman and famous art collector Philipp von Cobenzl and the diplomat Count Ludwig von Cobenzl spent time in the castle.In 1810, the castle was inherited by Count Michael Coronini von Cronberg, and in 1846 it was sold to the Windischgrätz family, who remained its owners until the end of World War II, when it was confiscated and nationalized by the Yugoslav Communist authorities and turned into a museum.## Hidden passageway.A vertical natural shaft, which Erasmus ordered to be enlarged, leads out of the original castle, and leads to the exit located at the top of the cliff,.

Golliwog. The golliwog, also spelled golliwogg or shortened to golly, is a doll-like character – created by cartoonist and author Florence Kate Upton – that appeared in children's books in the late 19th century, usually depicted as a type of rag doll. It was reproduced, both by commercial and hobby toy-makers, as a children's toy called the "golliwog", a portmanteau of "golly" and "polliwog", and had great popularity in the UK and Australia into the 1970s. The doll is characterised by jet black skin, eyes rimmed in white, exaggerated red lips and frizzy hair, a blackface minstrel tradition. Today the word.

Manufacturers who have used golliwogs as a motif (e.g. Robertson's marmalade in the UK) have either withdrawn them as an icon or changed the name. In particular, the use of alternative names such as "golly" and "golly doll" has risen due to association with the pejorative term "wog", which many dictionaries say probably derived from the golliwog.## In fiction.Florence Kate Upton was born in 1873 in Flushing, New York, United States, the.

Tetrahedron. of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid".Like all convex polyhedra, a tetrahedron can be folded from a single sheet of paper. It has two such nets.For any tetrahedron there exists a sphere (called the circumsphere) on which all four vertices lie, and another sphere (the insphere) tangent to the tetrahedron's faces.## Regular tetrahedron.A regular tetrahedron is a tetrahedron in which all four faces are equilateral triangles. It is one of the five regular Platonic solids, which have been known.

Tetrahedron. edge of the base. This follows from the fact that the medians of a triangle intersect at its centroid, and this point divides each of them in two segments, one of which is twice as long as the other (see ).For a regular tetrahedron with side length "a", radius "R" of its circumscribing sphere, and distances "di" from an arbitrary point in 3-space to its four vertices, we haveformula_7## Isometries of the regular tetrahedron.The vertices of a cube can be grouped into two groups of four, each forming a regular tetrahedron (see above, and also , showing one of the.

Other names for the same shape include bisphenoid, isosceles tetrahedron and equifacial tetrahedron.## Orthoschemes.A 3-orthoscheme is a tetrahedron where all four faces are right triangles. An orthoscheme is an irregular simplex that is the convex hull of a tree in which all edges are mutually perpendicular. In a 3-dimensional orthoscheme, the tree consists of three perpendicular edges connecting all four vertices in a linear path that makes two right-angled turns. The 3-orthoscheme is a tetrahedron having two.

Tetrahedron. its characteristic tetrahedron by its planes of symmetry.If the tetrahedron has edge length 2, its characteristic tetrahedron's six edges have lengths , , (the exterior right triangle face, the "characteristic triangle" of the tetrahedron), plus , , (edges that are the "characteristic radii" of the tetrahedron). The 3-edge path along orthogonal edges of the orthoscheme is , , , first from a tetrahedron vertex to an tetrahedron edge center, then turning 90° to an tetrahedron face center, then turning 90° to the tetrahedron center. The orthoscheme has four dissimilar right triangle faces. The exterior face is a 30-60-90 triangle which.

Then another volume formula is given byformula_25## Properties analogous to those of a triangle.The tetrahedron has many properties analogous to those of a triangle, including an insphere, circumsphere, medial tetrahedron, and exspheres. It has respective centers such as incenter, circumcenter, excenters, Spieker center and points such as a centroid. However, there is generally no orthocenter in the sense of intersecting altitudes.Gaspard Monge found a center that exists in every tetrahedron, now known as the Monge point: the point where the six midplanes of a tetrahedron intersect. A midplane is defined as a plane that is orthogonal to.

Tetrahedron. segment joining the midpoints of two opposite edges is called a "bimedian" of the tetrahedron. Hence there are four medians and three bimedians in a tetrahedron. These seven line segments are all concurrent at a point called the "centroid" of the tetrahedron. In addition the four medians are divided in a 3:1 ratio by the centroid (see Commandino's theorem). The centroid of a tetrahedron is the midpoint between its Monge point and circumcenter. These points define the "Euler line" of the tetrahedron that is analogous to the Euler line of a triangle.The nine-point circle of the general triangle has an.

Lorenz Lindelöf found that, corresponding to any given tetrahedron is a point now known as an isogonic center, "O", at which the solid angles subtended by the faces are equal, having a common.

What condition on 12 angles is necessary and sufficient for.

Tetrahedron. them to be the 12 angles of some tetrahedron? Clearly the sum of the angles of any side of the tetrahedron must be 180°. Since there are four such triangles, there are four such constraints on sums of angles, and the number of degrees of freedom is thereby reduced from 12 to 8. The four relations given by this sine law further reduce the number of degrees of freedom, from 8 down to not 4 but 5, since the fourth constraint is not independent of the first three. Thus the space of all shapes of tetrahedra is 5-dimensional.## Law of.

Gannet. Gannets are seabirds comprising the genus Morus in the family Sulidae, closely related to boobies.Gannets are large white birds with yellowish heads; black-tipped wings; and long bills. Northern gannets are the largest seabirds in the North Atlantic, having a wingspan of up to 2 (m). The other two species occur in the temperate seas around southern Africa, southern Australia, and New Zealand.## Etymology."Gannet" is derived from Old English "ganot" meaning "strong or masculine", ultimately from the same Old Germanic root as "gander".## Taxonomy."Morus" is derived from Ancient Greek "moros" "stupid" or "foolish" due to lack of fear shown by breeding.

They lack brood patches and use their webbed feet to warm the eggs. They reach maturity around 5 years of age. First-year birds are completely black, and subsequent subadult plumages show increasing amounts of white.## Northern gannets.The most important nesting ground for northern gannets is the United.

Aqua-Lung. Aqua-Lung was the first open-circuit, self-contained underwater breathing apparatus (or "scuba") to achieve worldwide popularity and commercial success. This class of equipment is now commonly referred to as a twin-hose diving regulator, or demand valve. The Aqua-Lung was invented in France during the winter of 1942–1943 by two Frenchmen: the engineer Émile Gagnan and the Naval Lieutenant (French: "lieutenant de vaisseau") Jacques Cousteau.

White stork. The white stork (Ciconia ciconia) is a large bird in the stork family, Ciconiidae. Its plumage is mainly white, with black on the bird's wings. Adults have long red legs and long pointed red beaks, and measure on average 100 – 115 (cm) from beak tip to end of tail, with a 155 – 215 (cm) wingspan. The two subspecies, which differ slightly in size, breed in Europe (north to Finland), northwestern Africa, southwestern Asia (east to southern Kazakhstan) and southern Africa. The white stork is a long-distance migrant, wintering in Africa from tropical Sub-Saharan Africa to as far south.

It includes about 20 towers reaching nearly 100 m of height built all around an elevated esplanade. That esplanade is paved with frescos that.

Front de Seine. can be seen only from the elevated floors of the towers. As opposed to Italie 13, the design of the towers is much more varied. The Hôtel Novotel Paris-Tour Eiffel (formerly known as Hôtel Nikkō), for instance, has red-encircled windows, while the Tour Totem consists of a stack of several glazed blocks.A newly redesigned shopping centre, the Centre commercial Beaugrenelle opened in 2013.Furthermore, while 13th arrondissement towers are predominantly residential and La Défense towers are predominantly commercial, the towers of the Front de Seine are of mixed commercial and residential use.

Whinchat. The whinchat ("Saxicola rubetra") is a small migratory passerine bird breeding in Europe and western Asia and wintering in central Africa. At one time considered to be in the thrush family, Turdidae, it is now placed in the Old World flycatcher family, Muscicapidae. Both sexes have a strong supercilium, brownish upper parts mottled darker, a pale throat and breast, a pale buff to whitish belly, and a blackish tail with white bases to the outer tail feathers, but in the breeding season, the male has an orange-buff throat and breast.The whinchat is a solitary species, favouring open grassy country with.

Whinchat. Africa before the migration northwards in spring. The whinchat is a common species with a wide range and the International Union for Conservation of Nature has classified it as being of "least concern".## Taxonomy and systematics.This species represents a fairly basal divergence of the genus "Saxicola". It retains the supercilium found in many Muscicapidae but lost in the more derived "Saxicola" species such as the European stonechat or African stonechat ("S. torquatus").As with other species of "Saxicola", it was formerly considered a member of the thrush family (Turdidae), but is now placed in the Old World flycatcher family Muscicapidae. It,.

Whinchat. and similar thrush-like Muscicapidae species, are often called chats.The English name is derived from "whin", the common gorse and "chat" referring to the nature of its calls. Its scientific name means "small rock-dweller", in reference to its habitat. "Saxicola" derives from Latin "saxum" ("rock") + "incola" ("dwelling"); "rubetra" is a Latin term for a small bird. No subspecies are recognised.Very rarely, hybridisation occurs between the whinchat and the Siberian stonechat ("Saxicola maurus"), with a case being reported in Finland in 1997. It has also been reported to hybridise with the European stonechat in western and southern Europe.## Description.The whinchat is.

Illicium verum. Illicium verum is a medium-sized evergreen tree native to northeast Vietnam and southwest China. A spice commonly called star anise, staranise, star anise seed, star aniseed, star of anise, Chinese star anise, or badian that closely resembles anise in flavor is obtained from the star-shaped pericarps of the fruit of "I. verum" which are harvested just before ripening. Star anise oil is a highly fragrant oil used in cooking, perfumery, soaps, toothpastes, mouthwashes, and skin creams. Until 2012, when they switched to using a bacterial source, Roche Pharmaceuticals used up to 90% of the world's annual star anise crop to.

Illicium verum. produce shikimic acid, a chemical intermediate used in the synthesis of oseltamivir (Tamiflu).## Etymology and nomenclature."Illicium" comes from the Latin "illicio" meaning "entice" or "seduce"."Verum" means "true" or "genuine".The name "badian" appears to derive, via French "badiane", from the apparently descriptive Chinese name for it, 八角, pinyin: "bājiǎo", lit. "eight horns". However, a derivation from the Persian "bādiyān," "fennel", exists, with the Oxford English Dictionary indicating that its origin before that is unknown.## Description.Leaves are aromatic, simple and lanceolate, obovate-elliptic or elliptic, size of 5–15 cm × 2–5 cm, coriaceous to thickly coriaceous. The leaves are 5–15 cm × 1.5–5.

Illicium verum. cm, apex acute, lower side pubescent. Flowers are solitary, bisexual, pink to dark red, axillary or subterminal. The perianth has lobes 7–12, arranged spirally; stamens number of 11–20, arranged spirally, with short, thick filaments; carpels usually 8, free, arranged in a single whorl. Flower peduncle size is 1.5–4 cm, tepals number range from seven to twelve, and are broadly elliptic to broadly ovate, anthers size is 1–1.5 mm, pollen grains trisyncolpate.The fruit is a capsule-like follicetum, star-shaped, reddish- brown, consisting of six to eight follicles arranged in a whorl. Each follicle is boat-shaped, 1–2 cm long, rough and rigid, color.

Illicium verum. reddish-brown, with 1 seed, opening along the ventral edge when ripe. carpels size of 10 mm long, boat-shaped; they are hard and wrinkled, containing one seed. Seeds are brown, compressed ovoid, smooth, shiny and brittle with approximate size of 8–9 mm × 6 mm.Differences with similar taxa:"Illicium anisatum" had smaller fruits that does not form a regular star due to the abortion of some carpels. Also fruit follicles are not swollen in the middle and had a more pointed apex. Also usually had more than 8 follicles and the fruit has weaker odour. The seeds in "Illicium anisatum" are flat.

Illicium verum. or almost spherical.## Use.## Culinary use.Star anise contains anethole, the same compound that gives the unrelated anise its flavor. Recently, star anise has come into use in the West as a less expensive substitute for anise in baking, as well as in liquor production, most distinctively in the production of the liqueur Galliano. Star anise enhances the flavour of meat.It is used as a spice in preparation of "biryani" and "masala chai" all over the Indian subcontinent. It is widely used in Chinese cuisine, and in Malay and Indonesian cuisines. It is widely grown for commercial use in China, India,.

Illicium verum. and most other countries in Asia. Star anise is an ingredient of the traditional five-spice powder of Chinese cooking. It is also a major ingredient in the making of "phở", a Vietnamese noodle soup.It is also used in the French recipe of mulled wine, called "vin chaud" (hot wine). If allowed to steep in coffee, it deepens and enriches the flavor. The pods can be used in this manner multiple times by the pot-full or cup, as the ease of extraction of the taste components increases with the permeation of hot water.## Drug precursor.Star anise is the major source of.

Illicium verum. the chemical compound shikimic acid, a primary precursor in the pharmaceutical synthesis of the antiinfluenza drug oseltamivir (Tamiflu). An industrial method for the production of shikimic acid using fermentation of "E. coli" bacteria was discovered in 2005, and applied in the 2009 swine flu pandemic to address Tamiflu shortages, also causing price increases for star anise as a raw material of shikimic acid. As of 2018, fermentation of "E. coli" was the manufacturing process of choice to produce shikimic acid for synthesis of Tamiflu. Study shows star anise can be used as anti quorum sensing and anti-biofilm agent in food.

Illicium verum. matrix.## Toxicity of related species."Illicium verum" is not toxic. However, other related species are toxic.Japanese star anise ("Illicium anisatum"), a similar tree, is highly toxic and inedible; in Japan, it has instead been burned as incense. Cases of illness, including "serious neurological effects, such as seizures", reported after using star anise tea, may be a result of deliberate economically motivated adulteration with this species. Japanese star anise contains the neurotoxin anisatin, which also causes severe inflammation of the kidneys (nephritis), urinary tract, and digestive organs when ingested.Swamp star anise "Illicium parviflorum" is a similar tree found in the Southern United.

Illicium verum. States, and due to its toxicity, it should not be used for folk remedies or as a cooking ingredient.

As a further punishment, he divided up the lands of North Yorkshire among his most loyal followers. Alan Rufus, of Brittany, received the borough of Richmond and began constructing.

Richmond Castle. the castle became the headquarters of the North Yorkshire Militia, and a military barracks block was constructed in the great courtyard. For two years, from 1908 to 1910, the castle was the home of Robert Baden-Powell, later founder of the Boy Scouts, while he commanded the Northern Territorial Army but the barracks building was demolished in 1931.
