White-breasted nuthatch. The white-breasted nuthatch (Sitta carolinensis) is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately 15.5 (cm) in length. Coloration varies somewhat along the species' range, but the are light blue-gray, with a black and nape in males, while females have a dark gray crown. The are whitish, with a reddish tinge on the lower abdomen. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a.

The species was once thought to be related to the white-cheeked nuthatch ("S. leucopsis") and Przewalski's nuthatch ("S. przewalskii"), two species from southern Asia, but is actually more closely related to the giant nuthatch ("S. magna"), also from Southeast Asia. The species enjoys a very wide distribution and its population is said to be increasing; the International Union for the Conservation of Nature therefore considers it to be of "least concern."## Taxonomy.The nuthatches are a genus, "Sitta", of small passerine birds which derive their English name from the tendency of some species to wedge.

White-breasted nuthatch. large insects or seeds into cracks, and then hack at them with their strong bills. "Sitta" is derived from "sittē", Ancient Greek for nuthatch, and "carolinensis" means "of Carolina" in Latin. The white-breasted nuthatch was first described by English ornithologist John Latham in his 1790 work, the "Index Ornithologicus". German ornithologist Hans Edmund Wolters proposed the division of the genus "Sitta" into subgenera in 1975–1982. The white-breasted nuthatch is placed in "Sitta" ("Leptositta") , alongside the white-cheeked nuthatch ("S. leucopsis") and Przewalski's nuthatch ("S. przewalskii").Nuthatch taxonomy is complex, with geographically separated species sometimes closely resembling each other. The white-breasted nuthatch.

White-breasted nuthatch. has an appearance and contact call similar to those of the white-cheeked nuthatch, of the Himalayas and was formerly considered to be conspecific with it. A study published in 2012 showed that four distinct lineages were genetically isolated from each other and could represent different species, recognizable by morphology and song. A molecular phylogeny published in 2014 and including all main species' lineages within nuthatches concluded that the white-breasted nuthatch was more closely related to the giant nuthatch ("S. magna") than to Przewalski's nuthatch, formerly regarded as possibly conspecific with it; Przewalski's nuthatch turned out to be basal in the.

White-breasted nuthatch. northeastern United States, at least 10% of females have black caps, but the proportion rises to 40–80% in the Rocky Mountains, Mexico and the southeastern U.S. Juveniles are similar to the adult, but duller plumaged.Three other, significantly smaller, nuthatches have ranges which overlap that of white-breasted, but none has white plumage completely surrounding the eye. Further distinctions are that the red-breasted nuthatch has a black eye line and reddish underparts, and the brown-headed and pygmy nuthatches each have a brown cap, and a white patch on the nape of the neck.## Geographical variation.The white-breasted nuthatch has nine subspecies, although the.

White-breasted nuthatch. differences are small and change gradually across the range. The subspecies are sometimes treated as three groups based on close similarities in morphology, habitat usage, and vocalizations. These groups cover eastern North America, the Great Basin and central Mexico, and the Pacific coastal regions. The subspecies of the western interior have the darkest upperparts, and eastern "S. c. carolinensis" has the palest back. The eastern form also has a thicker bill and broader dark cap stripe than the interior and Pacific races. The calls of the three groups differ, as described above.## Similar species.Only three other species of nuthatches inhabit.

White-breasted nuthatch. North America: the red-breasted nuthatch ("S. canadensis"), the pygmy nuthatch ("S. pygmaea") and the brown-headed nuthatch ("S. pusilla"), and their distributions overlap with those of the white-breasted nuthatch. They are, however, clearly distinct and much smaller, since they are the smallest nuthatches, measuring 10 centimeters long and weighing around 10 grams. The red-breasted nuthatch has reddish underparts and has a black stripe on the eye. The pygmy nuthatch and the brown-headed nuthatch have a brown crown with a white spot on the nape.## Distribution and habitat.The breeding habitat of the white-breasted nuthatch is woodland across North America, from southern Canada.

White-breasted nuthatch. pygmy and brown-headed nuthatches prefer pines.The presence of mature or decaying trees with holes suitable for nesting is essential, and trees such as oak, beech and hickory are favored in the east since they also provide edible seeds. White-breasted nuthatches seldom excavate their own nest holes like red-breasted nuthatches. Although suitable habitat is distributed continentally, it is discontinuous. The separate populations of this non-migratory species have diverged to form distinct regional subspecies.The white-breasted nuthatch, like most of its genus, is non-migratory, and the adults normally stay in their territory year-round. There may be more noticeable dispersal due to seed failure.

One bird landed on the RMS "Queen Mary" six hours' sailing east of New York City in October 1963.## Ecology and behavior.The white-breasted nuthatch often travels with small mixed flocks in winter. These flocks are led by titmice and chickadees, with nuthatches and downy woodpeckers as common attendant species. Participants in such flocks are thought to benefit in terms of foraging and predator avoidance. It is likely that the attendant species also access the information carried in.

White-breasted nuthatch. territory and either establish their own territory or become "floaters", unpaired birds without territories. It is probably these floaters which are mainly involved in the irregular dispersals of this species. This species of nuthatch roosts in tree holes or behind loose bark when not breeding and has the unusual habit of removing its feces from the roost site in the morning. It usually roosts alone except in very cold weather, when up to 29 birds have been recorded together.## Voice.Like other nuthatches, the white-breasted nuthatch is a noisy bird with a range of vocalizations. The male's mating song is a.

White-breasted nuthatch. strong legs and feet. All nuthatches are distinctive when seeking food because they are able to descend tree trunks head-first and can hang upside-down beneath twigs and branches.The white-breasted nuthatch is omnivorous, eating insects and seeds. It places large food items such as acorns or hickory nuts in crevices in tree trunks, and then hammers them open with its strong beak; surplus seeds are cached under loose bark or crevices of trees. The diet in winter may be nearly 70% seeds, but in summer it is mainly insects. The insects consumed by the white-breasted nuthatch include caterpillars, ants, and pest.

White-breasted nuthatch. species such as pine weevils, oystershell and other scale insects, and jumping plant lice. This bird will occasionally feed on the ground, and readily visits feeding stations for nuts, suet and sunflower seeds, the last of which it often takes away to store. The white-breasted nuthatch was also observed visiting raccoon latrines in order to find seeds.## Predators and parasites.Predators of adult nuthatches include owls and diurnal birds of prey (such as sharp-shinned and Cooper's hawks), and nestlings and eggs are eaten by woodpeckers, small squirrels, and climbing snakes such as the western rat snake. The white-breasted nuthatch responds to.

White-breasted nuthatch. and nine months.The white-breasted nuthatch's responses to predators may be linked to a reproductive strategy. A study compared the white-breasted nuthatch with the red-breasted nuthatch in terms of the willingness of males to feed incubating females on the nest when presented with models of predators. The models were of a sharp-shinned hawk, which hunts adult nuthatches, and a house wren, which destroys eggs. The white-breasted nuthatch is shorter-lived than the red-breasted nuthatch, but has more young, and was found to respond more strongly to the egg predator, whereas the red-breasted showed greater concern with the hawk. This supports the theory.

White-breasted nuthatch. for this species because it requires cavity sites for nesting; declines have been noted in Washington state, Florida, and more widely in the southeastern U.S. west to Texas. In contrast, the breeding range is expanding in Alberta, and numbers are increasing in the northeast due to regrown forest. The white-breasted nuthatch is protected under the Migratory Bird Treaty Act of 1918, to which the three countries in which it occurs (Canada, Mexico, and the United States) are all signatories.

Bursaria spinosa. Bursaria spinosa is a small tree or shrub in the family Pittosporaceae. The species occurs mainly in the eastern and southern half of Australia and not in Western Australia and the Northern Territory. Reaching 10 m (35 ft) high, it bears fragrant white flowers at any time of year but particularly in summer. A common understorey shrub of eucalyptus woodland, it colonises disturbed areas and fallow farmland. It is an important food plant for several species of butterflies and moths, particularly those of the genus "Paralucia", and native bees.## Description."Bursaria spinosa" has a variable habit, and can grow anywhere from.

Bursaria spinosa. first formally described by Antonio José Cavanilles in 1797 in his book, "Icones et Descriptiones Plantarum". It is known by many common names, including Australian blackthorn, blackthorn, Christmas bush, mock orange, native blackthorn, native box, native olive, prickly box, prickly pine, spiny box, spiny bursaria, sweet bursaria, thorn box and whitethorn. Summer flowering has given rise to the name (Tasmanian) Christmas bush in Tasmania and South Australia (not to be confused with "Prostanthera lasianthos"). Indigenous names recorded include "kurwan" in Coranderrk, Victoria, and "geapga" from Lake Hindmarsh Station."Bursaria spinosa" is highly variable in appearance and habit, as are other species.

For example, in 1893, Jules Alexandre Daveau, in Désiré Georges Jean Marie Bois's "Dictionnaire d'Horticulture", described varieties "inermis" (meaning "without spines") and "macrophylla" ("large leaves"), but var. "macrophylla" was a nomen illegitimum because it had already been used by William Jackson Hooker in 1834.A 1999 revision of the genus recognised only two subspecies and the names are accepted by the Australian Plant Census: "Bursaria spinosa" subsp. "lasiophylla" has shorter, wider leaves and smaller flowers than the autonym, only reaches a height of 5 (m), replaces the.

Bursaria spinosa. autonym on heavier clay soils, and occurs in New South Wales, Victoria and South Australia; "Bursaria spinosa" subsp. "spinosa" is a shrub or small tree to 5–10 (m) and is widely distributed across eastern Australia, including Queensland and Tasmania. Subspecies "lasiophylla" had been known as "Bursaria lasiophylla", first formally described in 1978 by Eleanor Marion Bennett, but reduced to a subspecies by Lindy Cayzer, Michael Crisp and Ian Telford in 1999.## Distribution and habitat."Bursaria spinosa" is widespread and common in the understorey of eucalypt woodland in all states of Australia, apart from Western Australia and the Northern Territory. In New.

Bursaria spinosa. South Wales, "B. spinosa" grows in dry to wet forest in all but the most arid parts of the state, and is sometimes a weed on cleared land. In the Sydney region, it grows on clay- and shale-based soils, as an understory plant in association with grey box ("Eucalyptus moluccana") and forest red gum ("E. tereticornis") as well as the grass "Themeda australis". It can form thickets on ungrazed farmland. In Victoria, the species is widespread and common throughout the state, except for the far north west, in heavier soils and in alpine areas, in South Australia it is widespread.

The larvae of the jewel beetle species "Astraeus crassus" live in tunnels in dead and dying branches. Caterpillars which feed on "Bursaria spinosa" include "Proselena annosana", two-ribbed arctiid ("Palaeosia bicosta") and bark looper moth ("Ectropis subtinctaria"), while those of the clouded footman ("Anestia ombrophanes") graze on algae and lichens which grow on the branches.The bright copper ("Paralucia aurifera") and ant species "Anonychomyrma nitidiceps" form a complex symbiotic relationship on "Bursaria spinosa". Butterflies lay their eggs on the underside of the leaves, and the caterpillars feed on the leaves.

Arch of Hadrian (Jerash). The Arch of Hadrian is an ancient Roman structure in Jerash, Jordan. It is an 11-metre high triple-arched gateway erected to honor the visit of Roman Emperor Hadrian to the city (then called Gerasa) in the winter of 129–130. The arch originally stood to almost 22 m and probably had wooden doors. It features some unconventional, possibly Nabataean, architectural features, such as acanthus bases. The columns are decorated with capitals at the bottom rather than the top. The monument served both as a commemorative arch and as an approach to Gerasa. The Arch's relative remoteness from the city walls points.

Arch of Hadrian (Jerash). to a plan for southward expansion of Gerasa during its heyday. The expansion, however, has not been implemented.## Description.In 2005, the arch was under restoration. Reconstruction was completed in 2007 and the arch is now roughly 21 meters high (about 36 feet), 37.45 meters long, and 9.25 meters wide. Each face of the arch has four engaged columns standing on pedestals and bases. Each pedestal is 2.20 meters high, 2.25 meters wide and 1.20 meters deep. The base of each column is topped by a row of acanthus leaves.There are three vaulted passageways on the lower level and each of.

Rhodiola rosea. Rhodiola rosea (commonly golden root, rose root, roseroot, Aaron's rod, Arctic root, king's crown, lignum rhodium, orpin rose) is a perennial flowering plant in the family Crassulaceae. It grows naturally in wild Arctic regions of Europe (including Britain), Asia, and North America ( N.B., Nfld. and Labrador, N.S., QC.; Alaska, Maine, N.Y., N.C., Pa., Vt), and can be propagated as a groundcover. Although "Rhodiola rosea" has been used in traditional medicine, there is no high-quality clinical evidence of its effectiveness to treat any disease. The United States Food and Drug Administration has issued several warnings to manufacturers of "R. rosea.

It is mostly a forest inhabiting species, however it is also found in treeless areas. In New.

Common brushtail possum. Zealand, possums favour broadleaf-podocarp near farmland pastures. In southern beech forests and pine plantations, possums are less common. Overall, brushtail possums are more densely populated in New Zealand than in their native Australia. This may be because Australia has more fragmented eucalypt forests and more predators. In Australia, brushtail possums are threatened by humans, tiger quolls, dogs, foxes, cats, goannas, carpet snakes, and powerful owls. In New Zealand, brushtail possums are threatened only by humans and cats. The IUCN highlight the population trend in Australia as decreasing.## Food and foraging.The common brushtail possum can adapt to numerous kinds of vegetation.

Common brushtail possum. New Zealand use many more den sites than those from Australia. Brushtail possums compete with each other and other animals for den spaces, and this contributes to their mortality. This is likely another reason why brushtail possum population densities are smaller in Australia than in New Zealand. Brushtail possums are usually not aggressive towards each other and usually just stare with erect ears. They vocalise with clicks, grunts, hisses, alarm chatters, guttural coughs, and screeching.## Reproduction and life history.The common brushtail possum can breed at any time of the year, but breeding tends to peak in spring, from September to.

Females have a gestation period of 16–18 days, after which they give birth to single young. A newborn brushtail possum is only 1.5 cm long and weighs only 2 g. As usual for marsupials, the newborn may climb, unaided, through the female's fur and into the pouch and attach to a.

In New Zealand's Ōrongorongo population, female young have been found to continue to associate with their mothers after weaning, and some inherit the prime den sites. A possible competition exists between mothers and daughters for dens, and daughters may be excluded from a den occupied by the mother. In forests with shortages of den sites, females apparently produce more sons, which do not compete directly for den sites, while in forests with plentiful den sites, female young are greater in number.## Relationship with humans.The common brushtail possum is considered a pest in some.

Like other possums, it is rather tolerant of humans and can sometimes be hand fed, although it is not encouraged, as their claws are quite sharp and can cause infection or disease to humans if scratched. It is a traditional food source for some indigenous Australians.## Australia.Its fur has been considered valuable and has been harvested.

Thermometer. in medicine, and in scientific research.## History.While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to approximate this closely, based on fixed points and interpolating thermometers. The most recent official temperature scale is the International Temperature Scale of 1990. It extends from 0.65 (K) to approximately 1358 (K).## Early developments.Various authors have credited the invention of the thermometer to Hero of Alexandria. The thermometer was not a single invention,.

Thermometer. however, but a development.Hero of Alexandria (10–70 AD) knew of the principle that certain substances, notably air, expand and contract and described a demonstration in which a closed tube partially filled with air had its end in a container of water. The expansion and contraction of the air caused the position of the water/air interface to move along the tube.Such a mechanism was later used to show the hotness and coldness of the air with a tube in which the water level is controlled by the expansion and contraction of the gas. These devices were developed by several European scientists.

Thermometer. graduations based on the melting and boiling points of water as standards and, in 1694, Carlo Renaldini (1615–1698) proposed using them as fixed points along a universal scale. In 1701, Isaac Newton (1642–1726/27) proposed a scale of 12 degrees between the melting point of ice and body temperature.## Era of precision thermometry.In 1714, scientist and inventor Daniel Gabriel Fahrenheit invented a reliable thermometer, using mercury instead of alcohol and water mixtures. In 1724, he proposed a temperature scale which now (slightly adjusted) bears his name. In 1742, Anders Celsius (1701–1744) proposed a scale with zero at the boiling point and.

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.

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.

Solar cell. 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. In 1883 Charles Fritts built the first solid state photovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient. Other milestones include: 1888 – Russian physicist Aleksandr Stoletov built the first cell based on the outer photoelectric effect discovered by Heinrich Hertz in 1887. 1905 –.

Fomitopsis pinicola. thick. Its surface is more or less smooth, at first orange-yellow with a white margin, later dark reddish to brown and then frequently with an orange margin. The pore surface is pale yellow to leather-brown, 3–4 pores per mm. It grows as thick shelves on live and dead coniferous or (less commonly) deciduous trees. The spores are pale yellow and smooth. The species also grows as a layer of tubes on the bottom of fallen wood.The fruiting body of "Fomitopsis pinicola" is called the "conk". It is a woody, pileate fruiting body with pores lined with basidia on its underside.

Fomitopsis pinicola. As in other polypores, the fruiting body is perennial with a new layer of pores produced each year on the bottom of the old pores. The pores are whitish when young and become somewhat brownish in age. This mushroom is inedible due to its woody texture, but it is useful as tinder.There is currently a splitting of "F. pinicola" occurring to isolate distinct species that have all previously been classified as "F. pinicola." DNA analysis supports splitting "F. pinicola" into three groups- "F. pinicola, F. mounceae, and F. schrenkii". "Fomitopsis pinicola" is found in Europe and Asia, "Fomitopsis mounceae" is.
