Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

Hermannsburg, Northern Territory
Hermannsburg, also known as Ntaria, is an Aboriginal community in Ljirapinta Ward of the MacDonnell Shire in the Northern Territory of Australia, ; west southwest of Alice Springs, on the Finke River, in the traditional lands of the Western Arrarnta people. Established as a Lutheran Aboriginal mission in 1877, linguist and anthropologist Carl Strehlow documented the local Western Arrernte language during his time there. The mission was known as Finke River Mission or Hermannsburg Mission, but the former term was later used to included a few more settlements, and from 2014 has applied to all Lutheran missions in Central Australia. The land was handed over to traditional ownership in 1982 under the ''Aboriginal Land Rights Act 1976'', and the area is now heritage-listed.

De Havilland Dragonfly
The de Havilland DH.90 Dragonfly is a 1930s British twin-engined luxury touring biplane built by the de Havilland Aircraft Company at Hatfield Aerodrome. Development The Dragonfly shares a clear family resemblance with the Dragon Rapide, but is smaller and has higher aspect ratio, slightly sweptback wings. The lower wing has a shorter span than the upper, unlike the DH.89, and the top of the engine nacelles protrude much less above its surface because the fuel tank had been moved to the lower centre section. Structurally, too they are different: the Dragonfly had a new preformed plywood monocoque shell and strengthened fuselage. It was designed as a luxury touring aircraft for four passengers and a pilot, with provision for dual controls. The first aircraft, ''G-ADNA'', first flew on 12 August 1935. The Dragonfly achieved maximum performance on low power, by using the new construction methods developed for the de Havilland Comet racer, and therefore was expensive to buy (£2,6 ...

King George V
George V (George Frederick Ernest Albert; 3 June 1865 – 20 January 1936) was King of the United Kingdom and the British Dominions, and Emperor of India, from 6 May 1910 until his death in 1936. Born during the reign of his grandmother Queen Victoria, George was the second son of Albert Edward, Prince of Wales, and was third in the line of succession to the British throne behind his father and his elder brother, Prince Albert Victor. From 1877 to 1892, George served in the Royal Navy, until the unexpected death of his elder brother in early 1892 put him directly in line for the throne. On Victoria's death in 1901, George's father ascended the throne as Edward VII, and George was created Prince of Wales. He became king-emperor on his father's death in 1910. George's reign saw the rise of socialism, communism, fascism, Irish republicanism, and the Indian independence movement, all of which radically changed the political landscape of the British Empire, which itself reached ...

Oodnadatta
Oodnadatta is a small, remote outback town and locality in the Australian state of South Australia, located north-north-west of the state capital of Adelaide by road or direct, at an altitude of . The unsealed Oodnadatta Track, an outback road popular with tourists, runs through the town. In the , there were 74 dwellings and the population was 318. Town facilities include a hotel, caravan park, post office, general stores, police station, hospital, fuel and minor mechanical repairs. The old railway station now serves as a museum. From the 1880s to the 1930s, Oodnadatta was a base for camel drivers and their animals, which provided cartage when the railway was under construction and along outback tracks before roads were established. After the railway line was lifted, Oodnadatta's role changed from that of a government service centre and supply depot for surrounding pastoral properties to a residential freehold town for Aboriginal families who, moving from cattle work, bought e ...

Nullarbor Plain
The Nullarbor Plain ( ; Latin: feminine of , 'no', and , 'tree') is part of the area of flat, almost treeless, arid or semi-arid country of southern Australia, located on the Great Australian Bight coast with the Great Victoria Desert to its north. It is the world's largest single exposure of limestone bedrock, and occupies an area of about . At its widest point, it stretches about from east to west across the border between South Australia and Western Australia. History Historically, the Nullarbor was seasonally occupied by Indigenous Australian people, the Mirning clans and Yinyila people. Traditionally, the area was called ''Oondiri'', which is said to mean "the waterless". The first Europeans known to have sighted and mapped the Nullarbor coast were Captain François Thijssen and Councillor of the Indies, Pieter Nuyts, on the Dutch East Indiaman '''t Gulden Zeepaert'' (the Golden Seahorse). In 1626–1627, they charted a stretch of the southern Australian coast eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Puss Moth
The de Havilland DH.80A Puss Moth is a British three-seater high-wing monoplane aeroplane designed and built by the de Havilland Aircraft Company between 1929 and 1933. It flew at a speed approaching 124 mph (200 km/h), making it one of the highest-performance private aircraft of its era. Design history The unnamed DH.80 prototype which first flew in September 1929 was designed for the flourishing private flying movement in the United Kingdom. It was a streamlined all-wooden aircraft fitted with the new de Havilland Gipsy III inverted inline engine that gave unimpeded vision across the nose without the protruding cylinder heads of the earlier Gipsy II engine. After the prototype was tested, the aircraft was redesigned with a fabric-covered steel-tube fuselage and as such redesignated the DH.80A Puss Moth. The first production aircraft flew in March 1930 and was promptly sent on a sales tour of Australia and New Zealand. Orders came quickly, and in the three years o ...

General Aircraft Monospar
The General Aircraft Monospar was a 1930s United Kingdom, British family of touring and utility aircraft built by General Aircraft Ltd (GAL). Design and development In 1929, the Monospar Company Ltd was formed to pursue new techniques of designing cantilever#Aircraft, cantilever wings, based on the work of Switzerland, Swiss engineer Helmuth J. Stieger, who headed the company. Helmuth John Stieger was born in Zurich in 1902, and educated at the Swiss Federal Polytechnic, and then at the Imperial College of Science in London. While working as a designer for William Beardmore and Company, he formed his own ideas about wing design, and evolved an improved method of building and stressing wings, for which he was later granted a British Patent in December 1927. The principle behind this Patent No. 306,220 was that the wing needed only one spar with torsion loads resisted by an efficient system of strong compression struts, with triangulated bracing in the form of thin wires.

Percival Lakes
The Percival Lakes form a string of "S" shaped ephemeral salt lakes in the north of Western Australia. They lie at the southern region of the Great Sandy Desert and east of Karlamilyi National Park. They stretch in an east-west direction for and north-south for . The surface elevation is . The Canning Stock Route runs in close proximity to some of the lakes, and crosses the salt pan of Tobin Lake near the eastern end. The lakes were named during the aerial expedition of Donald George Mackay in 1933, after the designer of the Percival Gull aircraft being used.

Gipsy Moth
The de Havilland DH.60 Moth is a 1920s British two-seat touring and training aircraft that was developed into a series of aircraft by the de Havilland Aircraft Company. Development The DH.60 was developed from the larger DH.51 biplane. The first flight of the ADC Cirrus powered prototype DH.60 Moth (registration ''G-EBKT'') was carried out by Geoffrey de Havilland at the works airfield at Stag Lane on 22 February 1925. The Moth was a two-seat biplane of wooden construction, it had a plywood covered fuselage and fabric covered surfaces, a standard tailplane with a single tailplane and fin. A useful feature of the design was its folding wings which allowed owners to hangar the aircraft in much smaller spaces. The then Secretary of State for Air Sir Samuel Hoare became interested in the aircraft and the Air Ministry subsidised five flying clubs and equipped them with Moths. The prototype was modified with a horn-balanced rudder, as used on the production aircraft, and wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
