Projectors: LCD Verses DLP (The downfall of DLP technology)

The most common question asked when acquiring a new projector for the home, office, or classroom is: would I purchase an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and different models available, it can be confusing for the buyer to pick between those technologies. The simple fact of the matter is that LCD projectors provide better image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with reproducing the same level of image quality.

Imagine a set of blinds in your household over your bedroom window. With the twist of a rod you can have the shutters open or closed, according to whether you want to let light in or not. That is exactly how an LCD projector works. Each pixel operates like a single shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is formed of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the point when the projector is switched on to when the image reaches your screen is vitally significant in regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which project the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then projected in a glass prism to deliver the projector image. Something to understad about LCD projectors is that all three colours are projected onto your wall at once. The way a DLP projector operates is very different and even the way an image appears is not the same. With DLP, white light from the lamp is directed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of forming an image forms a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to form the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into the single complete image. From LCD projectors, all colours are available all the time to offer the best brightness and fantastic colour accuracy. In DLP, only one colour is available at once, and so causing lower colour brightness and accuracy. Some DLP manufacturers have included a white segment for the colour wheel to improve all over brightness, but this goes and lessens colour accuracy.

I find in forums all the time that DLP offers a higher contrast ratio and thus must be better. For those unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is able to produce. DLP projectors do provide high contrast specifications compared to most LCD projectors. At one glance, this seems to be a plus, however, in the real world, the true black level is determined by the ambient light in the room when the projector is in use. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to see requires moving images, DLP projection technology also creates image errors, or ‘artifacts’. The most often seen artifact that a DLP projector creates with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change position between the time red, blue and green colours are shone. LCD projectors do not have this characteristic because the colours are delivered with the others. DLP manufacturers have formed 3DLP solutions using 3 chips to fix the colour break up error, but the price of these projectors make them almost impossible for most businesses and consumers.

Another difference between LCD and DLP is how they compensate for the refractive qualities of light. Think back to high school science, and they taught you how the different colours of light refract differing amounts when shone through the same lens. The disadvantage with DLP projectors is that they have the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light differently. Most of the time with a DLP projector, an extra yellow colour will show above and some blue will come up below an image containing something as simple as a straight black line. During manufacturing LCD projectors can be set to remove these effects on the projected image, as each colour is projected on its own LCD panels.

The isolated true advantage (excluding price) with choosing a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to mobility and has to be traded off against the image plusses of LCD projectors. If the outcome of the picture quality is important to you, then the solution is simple. Go with an LCD projector! LCD projectors will consistently show bright, colourful images with fewer image errors. If you wish to ask more about LCD technology in more detail, see this fabulous resource website: Explore 3LCD.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the initial yacht became a pleasure craft used first by royalty and secondly by the burghers on the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from private challenges. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English royalty in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 bet. Yachting rose as popular for the rich and aristocracy, but after that period the fashion did not last.

The first yacht association in the British Isles, the Water Club, was formed around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, with large naval panoply and gravity. The closest thing to racing boats was the “chase,” when the “fleet” pursued an imagined enemy. The club persisted, mostly as a social club, until 1765, and in 1828, after conglomerating with other clubs, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some stipulated method on the Thames in the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it was then known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been started at Cowes on the Isle of Wight in 1815, and royal funding made the Solent - the strait between the mainland and the Isle of Wight - the continued site of British yachting. The club at Cowes became the Royal Yachting Club, likewise at the rise of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing tests for great bids were held, and the society life was splendid. Ultimately Royal Yachting Club boats increased in size to bigger than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and went on when the English gained control. Sailing was largely for fun and rose to its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and created a standard of luxury and elegance for the later yachts in that area from the late 19th century. The first enduring American yacht group, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts took the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The design of large yachts was first largely affected by the win of America, which was created by George Steers for a association led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its win at Cowes in 1851. Early yachts were not designed and manufactured in a contemporary sense, with only a model being used. Not until the second half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the application of the study of aerodynamics do for the structure of sails and rigging what it had earlier done for hulls.

Because most of all sailboats had to be individually built, there was a desire for handicapping boats previous to the one-design class boats were built. Hence, a rating rule was decreed, which resulted in the International Rule, taken on in 1906 and amended in 1919. In modern times, one of the fastest blossoming areas in the sailing industry is that of one-design class boats. All boats in a one-design class are created to standard requirements in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing for these boats can be held on an even keel with no handicapping necessary. A perfect example is the uniform International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

As long as yachting belonged primarily for the aristocracy and the rich, cost was no issue, and the size of boats grew, in both length and weight. The ascendancy and desire of smaller boats came in the later half of the 19th century out of the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of smaller yachts. Thereafter in the 20th century, particularly after World War II, smaller racing and recreational craft became commonplace, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, craft of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam began to emulate sail power in public craft, the steam engine, and later the internal-combustion engine, were employed more and more in leisure boats. Sizeable power yachts were progressed to a high element, and long-distance travel became a preferred pastime of the affluent. The earliest power yachts were paddle-wheel boats; these then gave rise to boats powered by the completely submerged screw or propeller sort of propulsion. As well as naval and merchant boats, auxiliaries possessing both sail and power were the yacht archetype for many years. By the later half of the 20th century, many yachts were still auxiliaries, but the large part were solely power yachts with gasoline or diesel engines.

From the last decade of the 19th century there was a push in the construction of bigger steam yachts. Notably of these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 150. The Mayflower, purchased by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service in World War II.

As larger and more reliable internal-combustion engines were developed, many big boats started using them for power. The development of the diesel engine, with heavy oil for fuel, advanced in World War I. During the decade after that, big power-yacht creation grew, reaching a climax in the Orion (1930) at 3,097 tons. From that period the best auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of big power yachts declined in 1932, and the style after that was toward smaller, less expensive yachts. After World War II, a lot of small naval craft were traded by private owners for conversion to yachts. In the late 20th century, yachting had become a widespread popular activity enjoyed by thousands of yachtsmen personally owning and maintaining their own small recreational craft. The number of yachts and yachtsmen is increasing steadily, not only in the traditional locations on the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be differentiated by the effect they have on the allocation of income and wealth. A proportional tax is a kind that applies the same relative requirement on all the taxpayers—i.e., where tax liability and income move in equal levels. A progressive tax is recognisable by a greater than proportional growth in the tax onus in regard to the increase in income, and a regressive tax is recognised by a less than proportional growth in the relative burden. Ergo, progressive taxes are thought of as fighting a lack of equality in income distribution, while regressive taxes are seen to result in increasing these inequalities.

The taxes that are normally considered progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, can become less so within the upper-income class—especially if a taxpayer is permitted to lessen his tax base by claiming deductions or by leaving out some certain income elements from his taxable income. Proportional tax rates which are applied to lower-income categories would also be more progressive if such personal exemptions are declared.

Income measured over a given year does not absolutely give the most appropriate measure of taxpaying requirement. For example, transitory increases in income may be saved, and during temporary declines in income a taxpayer could opt to provide for consumption by taking from savings. So, if taxation is held in comparison alongside “permanent income,” it should be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (save those on luxuries) tend to be regressive, because the dissemination of own income consumed or spent on a specific good lowers as the level of personal income increases. Poll taxes (aka head taxes), levied as a standard amount per capita, patently are regressive.

It is hard to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to a lack of certainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden is dependant essentially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In analysing the economic purposes of taxation, it is necessary to distinguish between various points of tax rates. The statutory rates include those nominated in legislation; generally speaking these are marginal rates, but for some cases they are average rates. Marginal income tax rates indicate the fraction of incremental income that is taken by taxation when income is increased by one dollar. Thus, if tax liability increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislature commonly contain graduated marginal rates—i.e., rates that grow as income rises. Structured analysis of marginal tax rates are required to review provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) falls by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points more than indicated in the statutory rates. Since marginal rates display how after-tax income moves in response to changes in before-tax income, they are the necessary ones for assessing incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applied to income from business and capital, since it may be reliant on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates signify the part of total income that is demanded in taxation. The pattern of average rates is the one that is relevant for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates usually rise with income, both because personal allowances are permitted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received predominantly by high-income households may dwarf these effects, allowing regressivity, as shown by average tax rates that fall as income increases.

The Development of Data Projectors

The LCDs built for projection systems are typically small reflective or transmissive panels lit up by a bright arc lamp source. A line of lenses enlarges the reflected or transmitted image and displays it onto a screen. For front-projection systems the LCD is placed on the side of the screen as the viewer, but in rear-projection systems the screen is set off from behind. Projectors of greater cost and capability might be found with three separated LCD panels, reflecting separate red, green, and blue images that blend to form a coloured picture on the screen.

The increase in need for visual presentations has put a growth in emphasis on the switching speed of liquid crystals. This has required the manufacture of objects utilizing smectic liquid crystals, some of which emit a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most sophisticated smectic device. Within it the liquid crystal molecules are arranged in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and inside the layers the molecules are on a tilt, as displayed in the figure. The host liquid crystal holds optically active molecules, and a subtle outcome of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, analogous to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and throughout the plane of the layers. Therefore, there exists a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly coupled to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The respective change in optical properties can cause a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been publicized for big passive-matrix presentations, but their high cost and intricacy has stopped them from enjoying any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some promise for use as parts in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be made use of in time-sequential colour systems, in which costly colour filters are emulated with a coloured backlight that flashes red, green, and blue in fast pace (approx 100 cycles per second). For example, the liquid crystal could be switched to a transmissive state between the red and green periods but then to a nontransmissive state for the blue period, displaying the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of all furniture pieces, the chair may be primary. While the majority of other items (save for the bed) are intended to support objects, the chair supports a human form. The term chair is meant to be said here in the wider sense, from stool to throne to further pieces for example a bench or sofa, which can be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently definitive.

The social history of the chair is as exciting as its history as a creative craft. The chair is not simply a physical support and aesthetic item; it can also be symbolic of social standing. At the historical royal courts there were clear connotations between having a chair with arms, sitting on a chair with a back but no arms, and having to sit on a stool. During the 20th century, a director’s or manager’s chair has been seen as a symbol of superior standing, and in democratic government debate the speaker sits on a higher level.

In its furniture purpose, the chair is employed for a number of various forms. There are chairs created to match man’s age and physical condition (the high chair, the wheelchair) and to denote his rank in society (the executive chair, the throne). During the olden days there were chairs for births (birth chairs); since the 20th century, there have been chairs used for ending life (the electric chair). We design chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded up, chairs on wheels, and chairs on runners.

Our modern lifestyle has developed unique chairs in automobiles and aircraft. Each and every one of these chair forms has been perfected to fit to evolving human uses. Due to its unique link with man, the chair comes to its full meaning only when utilised. Whereas it doesn’t make any difference to one’s appreciation of a cupboard or a bureau if there are things inside or not, a chair is understood best and judged with a person sitting in it, because chair and sitter complement each other. Thus the several parts of a chair have been named as the elements of our human form: arms, legs, feet, back, and seat.

Because the fundamental work of a chair is to support the human body, its value is evaluated primarily from how well it measures up to this practical purpose. In the manufacture of a chair, the carpenter is restricted within certain static rules and principal measurements. Under these limits, however, the chair designer has marvellous freedom.

The history of the chair covered dates of several thousand years. There existed peoples that held distinctive chair types, expressions of the highest object in the spheres of skill and creativity. Among those civilisations, particular note should be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lives of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of skilled make, are found from tomb discoveries. The first of these two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have four legs shaped similar to those of a chosen animal, a curved seat, and with a sloping back supported above vertical stretchers. In this way a solid triangular design was made. There was from our view no marked change from the design of Egyptian thrones and chairs for regular peasantry. The only change lies in the decorative ornamentation, in the choice of pricier inlays. The Egyptian folding stool most probably was developed as an easily packed seat for officers. As a camp stool this stool stayed until much later points. But the stool also was designed as the role of a ceremonial seat, its technical function as a folding stool ignored or forgotten. This can from today’s evidence be observed, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are in the structure of folding stools but can’t be folded because the seats are created from wood. The plain manufacture of the folding stool, consisting of two frames that turn on metal bolts and support a seat of leather or fabric held between them, then appeared but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The best known of this type is the folding stool, crafted out of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is known not in any ancient fossil still around but as in a variety of pictorial objects. The archetype is the klismos seen on the Hegeso Stele at the Dipylon burial place by Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, only two of them were visible. These unusual legs were understood to be manufactured of bent wood and were therefore needed to bear extreme pressure with the weight of the sitter. The joints joining the legs to the frame of the seat would have had to be therefore super durable and were particularly pointed out.

The Romans borrowed from the Greek style; a number of casts of seated Romans are examples of a heavier and apparently rather crudely built klismos. Both designs, light or heavy, were revived in the Classicist era. The klismos style is evidenced in French Empire design, in English Regency, and in special brands of marked iconicism of Denmark and Sweden circa 1800.

China
The ancestry of the chair in China cannot be followed as long as the progression of the chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unscathed collection of drawings and artworks was kept, displaying the interiors and outside of Chinese households and the designs of furniture. Preserved also of the 16th century are some chairs made of wood or lacquered wood, that hold an astonishing resemblance to images of past chairs.

Just the same as in Egypt, two chair forms persisted in China: a chair of four legs and a folding stool. That four-legged chair can be seen both with and without arms though never missing its square seat and straight stiles (upright side supports) to hold up the back. In one style, it has been seen, the stiles could be lightly curved above the arms in order to sit right with the shape of the S-shaped back splat (the central upright of its back). Each of the three parts had been mortised on the yoke-like top rail. Though the style of this back splat had a foundation for English chairs during the Queen Anne period, wooden members that just to a restricted extent stabilise corner joints (as well as being loose in the result) signify a signature signatory to Chinese chairs. The four legs pass through the seat frame, which ends over the rounded staves. Members are round in section or has rounded edges—acknowledging maybe to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited seat. These chairs demanded of the sitter to stay stiff and upright; if too much pressure is exerted on the back, the chair has a way of falling over. In patriarchal Chinese homes of this epoch armchairs most likely were only for the senior persons, for they were given great esteem.

The Chinese folding stool is believed to have been brought to China from the West. It does not vary very much from the Egyptian or Scandinavian folding stools, but it possesses a variation in that the top rail is prettily joined to the two legs of the stool by means of a curved member, which is more often than not provided with metal mounts. From a Western perspective the resulting effect of both furniture designs is stylized. The constructive and aesthetic parts are combined in a manner that is all at once naïve and refined. The pieced-together appearance is a result of the fact that the individual members do not appear to have been joined together with either glue or screws, but have been mortised into one another and locked into place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also had its signature on the chair. Paintings display a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing between the layers, stitched to produce a pattern of small pads. The front board and a similar board at the back could be folded after unscrewing some little iron hooks. In this way the chair was an easily portable piece of furniture in traveling which, in the same era, held the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is seen in engravings of the interior of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this design of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not certain that the design actually was instigated in The Netherlands. Typically, the legs of the chair will be smooth, round in section, and of slender measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was made in considerable quantities, as evidenced from one of Abraham Bosse’s engravings, in which there is an entire row of this kind of chairs lined up against a wall. The form asserts itself by virtue of its elegant proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is to say, as developed in Paris around 1750—spread over most of Europe and has been imitated or copied during the mid-20th century. The chair owes such popularity to a combination of comfort and elegance. The seat adheres to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are tiny upholstered pads over the armrests. Smooth transitions made between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of relatively thick measurements; but each member is deeply molded, all extraneous wood has been taken away, and finer designs might be further embellished with very delicate and decorative carving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry might be used for the upholstery on the seat, back, and armrests; crosshatched cane is sometimes used instead of upholstery.

English chairs from the 18th century were more varied in form than the French. The French preference for stylistic uniformity, which spread from the most distinguished circles in Paris and Versailles within most of France and found favour in several parts of the Continent, had no parallel in England. Prior to 1740, the most commonly used wood was walnut; thereafter, and for the rest of the century, it was mahogany. Walnut, though beautiful in hue, was soft and therefore less suited to wood carving than to rounded, curving forms. Outer surfaces, such as the back and seat frame, were usually veneered. During the walnut period, highly overstuffed armchairs, covered with leather or embroidered material, were also developed. The best upholstery of this period is precisely and firmly modelled and accentuated by braiding or tacks. When imports of mahogany became common, no specifically new chair designs appeared, but the character of the woodwork changed. Mahogany, having a firmer, closer grain, could be cut thinner, which meant that individual parts of the chair could be more slender in shape. Mahogany also lent itself better to carving than walnut. Carving was concentrated more on the arms and back than on the legs, which as a rule were straight and smooth with chamfered (bevelled) edges and molding. There was a wealth of variety in chairback designs, featuring elegant, pierced, vase-shaped splats or two upright posts connected by horizontal slats (ladderback).

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became popularised and was widely distributed throughout the world.

Late 18th to 20th century
During the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

In cheaper brands of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, indicate that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the function of a business. Bookkeeping provides the information from which accounts are made but is a separate process, required prior to accounting.

Essentially, bookkeeping provides two kinds of information: (1) the current value, or equity, of the business and (2) changes in value—profit or loss—taking place in the entity from a single time.

Management officials, investors, and credit grantors all demand this information: management to interpret the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the results of business operations and make decisions for buying, holding, and selling securities; and credit grantors to judge the financial statements of a business in deciding whether to allow a loan.

Bits and pieces of financial and numerical records can be found for almost every nation with a commercial background. Records of business contracts were uncovered in the remains of Babylon, and accounts for both farms and estates had been made in ancient Greece and Rome. The dual-entry manner of bookkeeping began with the progression of the entrepeneurial republics of Italy, and tutorials for bookkeeping were produced during the 15th century in various Italian cities.

During the late 18th and early 19th centuries, the Industrial Revolution permitted a significant stimulus to accounting and bookkeeping.

The progression of manufacturing, trading, shipping, and subsidiary services made perfect financial recordkeeping a paramount factor. The ancestry of bookkeeping, in fact, resembles the history of commerce, industry, and government and, in part, assisted to shape it. The international revolution of industrial and commercial activity required more sophisticate decision-making methods, which in its turn demanded better sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government regulation became more detailed and resulted in higher need for information; businesses had to have available information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the demand for bookkeeping for their own operations became larger.

While bookkeeping methodology can be rather multifaceted, all of it is based on two styles of books utilised in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so forth), and the ledger contains the details of individual accounts. The daily records kept in the journals are entered in the ledgers.

At the end of each month, as a general rule, an income statement and a balance sheet are constructed from the trial balance posted within the ledger. The point of the income statement or profit-and-loss statement is to present an analysis of any changes that have occurred in the entity equity resulting from the transactions of the period. The balance sheet shows the financial condition of the enterprise at a particular point in terms of assets, liabilities, and the ownership equity.

Intense Pulsed Light Photorejuvenation

IPL (Intense Pulsed Light) or photorejuvenation therapy is a light based technology which treats several skin conditions in one treatment.

It works in the deeper layers of the skin where traditional skincare cannot reach, thus achieving a far superior result in a shorter time frame.

Skin concerns such as pigmentation, freckling, sun damage, capillaries, redness, acne scarring and rosacea may be treated with photorejuvenation.

Pulses of light are applied to the skin either in single zone or more commonly over the whole area to provide a uniform result.

The treatments remove most types of sun induced pigmentation like freckling, age spots and sun damage. By lessening the darker pigmentation IPL leaves the skin with a more even tone.

Vascular skin concerns including capillaries, redness, acne scarring and rosacea are also targeted by the broad wavelengths of light.

As most people will have several skin concerns, this treatment has become popular as it can address them all. The IPL photorejuvenation also stimulates the production of collagen which will plump and smooth the texture of the skin, improving fine lines, wrinkles and pitted scarring.

The most common treatment areas are face, neck, décolletage/chest area and backs of hands.

There is little or no downtime involved with photorejuvenation. Most people will experience some redness and heat in the area which subsides in several hours after treatment.

The darker areas of pigment may form tiny ‘pigment crusts’ which lift off in a few days revealing the result underneath. As the skin is not broken or damaged it is fine to wear make-up, though exfoliation via mechanical scrubs and AHA/glycolics is to be avoided for a week after the IPL treatment.

IPL Photorejuvenation treatments can be utilised as a once off treatment, however a course of treatments will promote the best results.

A progressive result can be expected with a change usually noticed within a week after a session. It is of utmost importance to wear sunscreen in between and after treatments as most of the damage on skin is caused by UV exposure and to prolong the result from the IPL photorejuvenation this is essential.
