Deelfontein
Deelfontein is a village in the Great Karoo, Northern Cape, region of South Africa on the route of the Pretoria to Cape Town railway. It primarily developed to service the railway due to its good water supply for steam locomotives, and is currently the location of a passing loop on the single-track line. In 1900 a British military field hospital, the Imperial Yeomanry Hospital, was constructed for casualties from the Second Boer War. The location was chosen for its communications and dry climate, and its proximity to De Aar, then the centre of hostilities. Alfred Downing Fripp was Chief Medical Officer. The hospital was unusual in pioneering the use of x-ray diagnosis. The surgeon-radiographer in charge, Major John Hall-Edwards, achieved eminence in this field, though he subsequently lost an arm through x-ray damage. The hospital, with a capacity for some 800 patients, largely comprised tents and prefabricated huts; at the cease of hostilities, materials from the latter were us ...

Richmond, Northern Cape
Richmond is a town in the central Karoo region of the Northern Cape Province, South Africa. It is situated on the main N1 route. Origin, architecture and history The town was established in 1843 in South Africa's inland plateau. It was founded to meet the religious needs of a growing farming community, but unlike most Karoo towns the church was not built as the physical focal point of the village; rather, the centrepiece is the village square. Unusually for this arid region, it was built astride a river which has been cited as the reason for the irregular street grid. The town has a substantial number of well-preserved houses and public buildings of Victorian and Edwardian Karoo style, with additions of verandahs dating from the 1920s. The Dutch Reformed Church building, the spiritual if not the physical centre around which the town evolved, dates from 1847, with a tower completed in 1909. It celebrated a centenary in 2009. The naming of the town originated in the desire of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wrong-side Failure
A wrong-side failure describes a failure condition in a piece of railway signalling equipment that results in an unsafe state. A typical example would be a signal showing a 'proceed' aspect (e.g. green) when it should be showing a 'stop' or 'danger' aspect, resulting in a "false clear". (The converse is a right-side failure, where even with any reduction the resulting state is safe overall.) Example of how a wrong-side failure may occur Consider a relay that has to energize to show a green light. If a wire breaks, or the battery is drained, then the relay will de-energize and the signal will show a red light, which is fail-safe. If a stray wire from another circuit touches the wire connected to that same relay, then that would be a wrong side failure, which is potentially dangerous. This stray wire can be guarded against by ensuring that the insulation on the relay wire is of good quality, and that all terminals are locked away. In addition, the relay may be double-switched ...

John Hall-Edwards
John Francis Hall-Edwards FRSE (19 December 1858 – 15 August 1926) was a British doctor and pioneer in the medical use of X-rays in the United Kingdom. Life Hall-Edwards was the son of John Edwards, and was born on Moseley Road, Kings Norton near Birmingham. He attended King Edward VI Grammar School in Birmingham. He then studied medicine, apprenticing under Prof Richard Hill Norris at Queens College Medical School. Norris was both a surgeon and keen amateur photographer, being an early user of the dry-plate process, and he familiarised Hall-Edwards with photographic techniques. Hall-Edwards was licensed to practice medicine by the Royal College of Physicians of Edinburgh. From around 1885 he shows a strong interest in photography and was President of the Midland Photographic Club 1891-93. In 1895 he was made an Honorary Member of the Royal Photographic Society following a lecture to the London Camera Club. Initially his work focussed on photography through microscope ...

De Aar
De Aar is a town in the Northern Cape province of South Africa. It has a population of around 42,000 inhabitants.

Passing Loop
A passing loop (UK usage) or passing siding (North America) (also called a crossing loop, crossing place, refuge loop or, colloquially, a hole) is a place on a single line railway or tramway, often located at or near a station, where trains or trams travelling in opposite directions can pass each other. Trains/trams going in the same direction can also overtake, provided that the signalling arrangement allows it. A passing loop is double-ended and connected to the main track at both ends, though a dead end siding known as a refuge siding, which is much less convenient, can be used. A similar arrangement is used on the gauntlet track of cable railways and funiculars, and in passing places on single-track roads. Ideally, the loop should be longer than all trains needing to cross at that point. Unless the loop is of sufficient length to be dynamic, the first train to arrive must stop or move very slowly, while the second to arrive may pass at speed. If one train is too long for ...

Port Elizabeth, Eastern Cape
Gqeberha (), formerly Port Elizabeth and colloquially often referred to as P.E., is a major seaport and the most populous city in the Eastern Cape province of South Africa. It is the seat of the Nelson Mandela Bay Metropolitan Municipality, South Africa's second-largest metropolitan district by area size. It is the sixth-most populous city in South Africa and is the cultural, economic and financial centre of the Eastern Cape.

The Donkin memorial in the CBD of the city bears testament to this. Port Elizabeth was established by the government of the Cape Colony when 4,000 British colonists settled in Algoa Bay to strengthen the border region between the Cape Colony and the Xhosa people, Xhosa. It is nicknamed "The Friendly City" or "The Windy City". In 2019, the Eastern Cape Geographical Names Committe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Township (South Africa)
In South Africa, the terms township and location usually refer to the often underdeveloped racially segregated urban areas that, from the late 19th century until the end of apartheid, were reserved for non-whites, namely Black Africans, Coloureds and Indians. Townships were usually built on the periphery of towns and cities. The term ''township'' also has a distinct legal meaning in South Africa's system of land title, which carries no racial connotations. Townships for non-whites were also called ''locations'' or ''lokasies'' in Afrikaans and are often still referred to by that name in smaller towns. The slang term "kasie/kasi", a popular short version of "lokasie" is also used. Townships sometimes have large informal settlements nearby. History Early development During the first half of the twentieth century, a clear majority of the black population in major urban areas lived in hostels or servants' accommodations provided by employers and were mostly single men.

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
