List Of Nuttall Mountains In England And Wales
This is a list of Nuttall mountains in England and Wales by height. Nuttalls are defined as peaks above in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above ; a mix of imperial and metric thresholds. The Nuttall classification was suggested by Anne and John Nuttall in their 1990 two–volume book, "The Mountains of England and Wales". The list was updated with subsequent revised editions by the Nuttalls. Because of the prominence threshold of only , the list is subject to ongoing revisions. In response, Alan Dawson introduced the Hewitts, with a higher prominence threshold of . This was the prominence threshold that the UIAA set down in 1994 for an "independent" peak. In 2010, Dawson replaced his Hewitts with the fully "metric" Simms, consisting of a height threshold of , and a prominence threshold of . However, both the Nuttall and Hewitt classifications have become popular with peak baggers, and both remain in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuttall Ornithological Club
The Nuttall Ornithological Club is the oldest ornithology organization in the United States. History The club initially was a small informal group of William Brewster's childhood friends, all of whom shared his interest in ornithology. These friends included Daniel Chester French, Ruthven Deane and Henry Henshaw. In 1872, Henshaw suggested that the group meet on a regular weekly schedule at Brewster's house in Cambridge, Massachusetts. On November 17, 1873, the group, which had expanded to include Henry Augustus Purdie, William Earl Dodge Scott, Francis P. Atkinson, Harry Balch Bailey, Ernest Ingersoll, and Walter Woodman, met to formally establish the first American ornithological club.Davis, William E. History of the Nuttall Ornithological Club, 1873-1986. Cambridge, 1987 They named their club after the botanist and zoologist Thomas Nuttall who published the first field guide for North American birds, ''Manual of the Ornithology of the United States and of Canada'' (1832 ...

Geiger–Nuttall Law
In nuclear physics, the Geiger–Nuttall law or Geiger–Nuttall rule relates the decay constant of a radioactive isotope with the energy of the alpha particles emitted. Roughly speaking, it states that short-lived isotopes emit more energetic alpha particles than long-lived ones. The relationship also shows that half-lives are exponentially dependent on decay energy, so that very large changes in half-life make comparatively small differences in decay energy, and thus alpha particle energy. In practice, this means that alpha particles from all alpha-emitting isotopes across many orders of magnitude of difference in half-life, all nevertheless have about the same decay energy. Formulated in 1911 by Hans Geiger and John Mitchell Nuttall as a relation between the decay constant and the range of alpha particles in air, in its modern form the Geiger–Nuttall law is :\log_\lambda=-a_1\frac+a_2 where ''λ'' is the decay constant (λ = ln2/half-life), ''Z'' the atomic number, ''E'' th ...

Codex Zouche-Nuttall
The Codex Zouche-Nuttall or Codex Tonindeye is an accordion-folded pre-Columbian document of Mixtec pictography, now in the collections of the British Museum. It is one of about 16 manuscripts from Mexico that are entirely pre-Columbian in origin. The codex derives its name from Zelia Nuttall, who first published it in 1902, and Baroness Zouche, its donor. Description The Codex Zouche-Nuttall was probably made in the 14th century and is composed of 47 sections of animal skin with dimensions of 19 cm by 23.5 cm. The codex folds together like a screen and is vividly painted on both sides, and the condition of the document is by and large excellent. It is one of three codices that record the genealogies, alliances and conquests of several 11th and 12th century rulers of a small Mixtec city-state in highland Oaxaca, the Tilantongo kingdom, especially under the leadership of the warrior Lord Eight Deer Jaguar Claw (who died in the early twelfth century at the age of fifty-two ...

Window Function
In signal processing and statistics, a window function (also known as an apodization function or tapering function) is a mathematical function that is zero-valued outside of some chosen interval, normally symmetric around the middle of the interval, usually near a maximum in the middle, and usually tapering away from the middle. Mathematically, when another function or waveform/data-sequence is "multiplied" by a window function, the product is also zero-valued outside the interval: all that is left is the part where they overlap, the "view through the window". Equivalently, and in actual practice, the segment of data within the window is first isolated, and then only that data is multiplied by the window function values. Thus, tapering, not segmentation, is the main purpose of window functions. The reasons for examining segments of a longer function include detection of transient events and time-averaging of frequency spectra. The duration of the segments is determined in ea ...

BAM Nuttall
BAM Nuttall Limited (formerly known as Edmund Nuttall Limited) is a construction and civil engineering company headquartered in Camberley, United Kingdom. It has been involved in a portfolio of road, rail, nuclear, and other major projects worldwide. It is a subsidiary of the Dutch Royal BAM Group. History The company was founded by James Nuttall Snr in Manchester in 1865, to undertake engineering works associated with infrastructure developments, such as the Manchester Ship Canal, which opened in 1894 and the narrow gauge Lynton and Barnstaple Railway, which opened in 1898. In the 1900s and 1910s James Nuttall Snr's two sons— Sir Edmund Nuttall, 1st Baronet (1870–1923), who was made a baronet in 1922, and James Nuttall (1877–1957)—built the company into a nationwide business. In the 1920s and 1930s the company was run by Sir Edmund's son, Sir Keith Nuttall, 2nd Baronet (1901–1941), who served in the Royal Engineers in the Second World War. Other members of the family ...

Nuttall's Toothwort
''Cardamine nuttallii'' is a species of cardamine known by the common name Nuttall's toothwort. It is native to western North America from British Columbia to California, where it grows in moist mountain habitats. Description ''Cardamine nuttallii'' is a perennial herb growing from a small, white rhizome. It produces a thin, unbranching stem under 20 centimeters tall. The leaves are smooth or lobed along the edges and sometimes divided into a few smaller leaflets. The inflorescence bears generally more than one pale purple, pink, or occasionally white flowers with petals each over a centimeter long. The fruit is a silique up to 4 centimeters long.
