Gabriel Sudan
Gabriel Sudan (April 14, 1899 – June 22, 1977) was a Romanian mathematician, known for the Sudan function, an important example in the theory of computation, similar to the Ackermann function. Born in Bucharest, Sudan received his Ph.D. from the University of Göttingen in 1925 for his thesis ''Über die geordneten Mengen'' ("On the theory of ordered sets"), supervised by David Hilbert. He taught at the Polytechnic University of Bucharest from 1941 until his retirement, in 1966. Sudan constructed the function that bears his name with the same aim as Wilhelm Ackermann: to solve in the affirmative a problem raised by Hilbert. The Ackermann and Sudan functions are chronologically the first examples of recursive functions which are not primitive recursive In computability theory, a primitive recursive function is roughly speaking a function that can be computed by a computer program whose loops are all "for" loops (that is, an upper bound of the number of iterations of e ...

Sudan Function
In the theory of computation, the Sudan function is an example of a function that is recursive, but not primitive recursive. This is also true of the better-known Ackermann function. The Sudan function was the first function having this property to be published. It was discovered (and published ) in 1927 by Gabriel Sudan, a Romanian mathematician A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems.

Sudan (tribe)
The Sudan ( ar, السودان) (singular Al Suwaidi ar, السويدي) is an Arab tribe of Qahtanite origin in Qatar and the United Arab Emirates (UAE), and other Gulf states. The settled Sudan at the turn of the 20th century numbered some 405 houses in Abu Dhabi and Batin, 250 houses in Dubai, 300 in Sharjah and 12 in Ajman. The family also settled the islands of the Persian Gulf, with some 20 houses on Abu Musa and 40 families living on Sirri Island. Some 5,000 strong, the tribe was mostly settled in the coastal areas of the Trucial States. The Sudan mostly subsisted on fishing and pearling and did not own date gardens in the inland oases. The Sudan in Qatar The Sudan played an important part in the founding of Bida’a on Qatar’s eastern coast. The oldest quarter of the town was settled by members of the tribe from Abu Dhabi and Oman in 1766. In 1801 the British representative in Muscat, David Seton, suspected the tribe of being involved in piracy and sailed with the ...

Sudan (ship)
PS ''Sudan'' is a passenger-carrying side-wheel paddle steamer on the River Nile in Egypt. Along with PS ''Arabia'', she was one of the largest river steamers in Thomas Cook's Nile fleet. Some scenes of the ITV television film of Agatha Christie's ''Death on the Nile'' were filmed aboard ''Sudan''. The steamer spent the latter years of the 20th century laid up and in deteriorating condition but new French owners bought her in 2000 and returned her to service in 2001. In 2004, she was again used for an adaptation of ''Death on the Nile ''Death on the Nile'' is a work of detective fiction by British writer Agatha Christie, published in the UK by the Collins Crime Club on 1 November 1937 and in the US by Dodd, Mead and Company the following year.

Sudan (rhinoceros)
Sudan (1973 – 19 March 2018) was a captive northern white rhinoceros (''Ceratotherium simum cottoni'') that lived at the Dvůr Králové Zoo in the Czech Republic from 1975 to 2009 and the rest of his life at the Ol Pejeta Conservancy in Laikipia, Kenya. At the time of his death, he was one of only three living northern white rhinoceroses in the world, and the last known male of his subspecies. Sudan was euthanised on 19 March 2018, after suffering from "age-related complications".Eyder Peralt"Sudan, World's Last Male Northern White Rhino, Dies" ''NPR'', 20 March 2018.

Sudan Black B
Solvent Black 3 is an azo dye. It is a non-fluorescent, relatively thermostable lysochrome (fat-soluble dye) diazo dye used for staining of neutral triglycerides and lipids on frozen sections and some lipoproteins on paraffin sections. It has the appearance of a dark brown to black powder with maximum absorption at 596–605 nm and melting point 120–124 °C. It stains blue-black. Applications Solvent Black 3 is used for a wide variety of commercial applications. In the laboratory, Solvent Black 3 is used for Sudan staining. Similar dyes include Oil Red O, Sudan III, and Sudan IV. It can be used to stain some other materials than the other Sudan dyes, as it is not so specific to lipids. It is used is in fingerprint enhancement. It is useful for detecting fats that are contaminated with oil and grease. In differentiating haematological disorders, it will stain myeloblasts but not lymphoblasts __NOTOC__ A lymphoblast is a modified naive lymphocyte with altered cell morph ...

Sudan IV
Sudan IV (C24H20N4O) is a lysochrome (fat-soluble dye) diazo dye used for the staining of lipids, triglycerides and lipoproteins on frozen paraffin sections. It has the appearance of reddish brown crystals with melting point 199 °C and maximum absorption at 520(357) nm. Sudan IV is one of the dyes used for Sudan staining. Similar dyes include Oil Red O, Sudan III, and Sudan Black B. Staining is an important biochemical technique, offering the ability to visually qualify the presence of the fatty compound of interest without isolating it. For staining purposes, Sudan IV can be made up in propylene glycol. Alternatively, authors have reported using the dye saturated in isopropyl alcohol, 95% ethanol, or 0.05% by weight in acetone:ethanol:water (50:35:15). The idea is to use a moderately apolar solvent to solubilize the dye allowing it to partition into the highly apolar fat without the solvent solubilizing the fat to be stained. Sudan I, Sudan III, and Sudan IV have bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sudan III
Sudan III is a lysochrome (fat-soluble dye) diazo dye. It is structurally related to azobenzene. Uses It is used to color nonpolar substances such as oils, fats, waxes, greases, various hydrocarbon products, and acrylic emulsions. Its main use is as a fuel dye in the United States of America mandated by the Internal Revenue Service (IRS) to distinguish low-taxed heating oil from automotive diesel fuel, and by the United States Environmental Protection Agency (EPA) to mark fuels with higher sulfur content; it is a replacement for Solvent Red 26 with better solubility in hydrocarbons. The IRS requires "a concentration spectrally equivalent to at least 3.9 pounds of... Solvent Red 26 per thousand barrels of fuel" (); the concentrations required by EPA are roughly 5 times lower. Biological staining Sudan III is a dye used for Sudan staining. Similar dyes include Oil Red O, Sudan IV, and Sudan Black B. They are used for staining of triglycerides in frozen sections, an ...
