NB (TV Programme)
''NB'' is a Scottish television programme about the arts and what's on guide in the entertainment world within the Central belt of Scotland. History NB debuted in 1989 and aired until it ended in 1997. Produced by Scottish Television, it was largely conceived by its producer Donny O'Rourke, and presented by a young, all-Scottish cast. '' Daily Record'' television critic Paul English wrote that the show "helped shape the taste of Scotland's clubbers, gig-goers, opera lovers and theatre-buffs too". Series 23 series were produced, with most years having 3 series each. * Series 1: 27 April - 1 June 1989: 6 episodes * Series 2: 2 Octoberhttps://news.google.com/newspapers?id=SNpAAAAAIBAJ&sjid=x6YMAAAAIBAJ&pg=6582%2C112928 - November 1989 Presenters * JaniceForsyth (1989–1995) * Bryan Burnett (1989–1993) * Allan Campbell (1989–1997) * Dougie Vipond (1993–1997) * Sally Gray Constance Vera Browne, Baroness Oranmore and Browne (''née'' Stevens; 14 February 1915 †...

NB Class
The Commonwealth Railways NB class originated in a shipment of four 0-6-0, gauge, saddle tank steam locomotives built by the Vulcan Iron Works of Wilkes-Barre, Pennsylvania. They were imported to Australia in 1916 for construction work at the naval base at Henderson, Western Australia. Their tractive effort was 9500 pounds. In 1925 two of them (builder's numbers 2532 and 2533) were acquired by the Commonwealth Railways and placed in service on the Central Australian Railway as NB29 and NB30 respectively. After shunting for two decades at Quorn, where they were nicknamed "pugs", the two locomotives were set aside. NB29 was written off in 1946 and scrapped in 1958. NB30 was written off in 1950. Conversion to diesel – NB30 In 1957, the frame and wheels of NB30 were used as the basis of a small diesel-hydraulic locomotive designed and built at Commonwealth Railways' Port Augusta workshops.Specifications included power output of – from a General Motors model 6/7 ...

National Battlefield
National Military Park, National Battlefield, National Battlefield Park, and National Battlefield Site are four designations for 25 battle sites preserved by the United States federal government because of their national importance. The designation applies to "sites where historic battles were fought on American soil during the armed conflicts that shaped the growth and development of the United States...." There are eleven National Battlefields (NB), nine National Military Parks (NMP), four National Battlefield Parks (NBP), and one National Battlefield Site (NBS). The National Park Service does not distinguish among the four designations in terms of their preservation or management policies. Seventeen sites are from the American Civil War, four from the American Revolutionary War, one from the War of 1812, one from the French and Indian War, and two were attacks on Native Americans. In 1890, Chickamauga and Chattanooga National Military Park was the first such site created by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narrowboat
A narrowboat is a particular type of canal boat, built to fit the narrow locks of the United Kingdom. The UK's canal system provided a nationwide transport network during the Industrial Revolution, but with the advent of the railways, commercial canal traffic gradually diminished and the last regular long-distance transportation of goods by canal had virtually disappeared by 1970. However, some commercial traffic continued. From the 1970s onward narrowboats were gradually being converted into permanent residences or as holiday lettings. Currently, about 8580 narrowboats are registered as 'permanent homes' on Britain's waterway system and represent a growing alternative community living on semi-permanent moorings or continuously cruising. For any boat to enter a narrow lock, it must be under wide, so most narrowboats are nominally wide. A narrowboat's maximum length is generally , as anything longer will be unable to navigate much of the British canal network, because the n ...

NB (programming Language)
B is a programming language developed at Bell Labs circa 1969 by Ken Thompson and Dennis Ritchie. B was derived from BCPL, and its name may possibly be a contraction of BCPL. Thompson's coworker Dennis Ritchie speculated that the name might be based on Bon, an earlier, but unrelated, programming language that Thompson designed for use on Multics. B was designed for recursive, non-numeric, machine-independent applications, such as system and language software. It was a typeless language, with the only data type being the underlying machine's natural memory word format, whatever that might be. Depending on the context, the word was treated either as an integer or a memory address. As machines with ASCII processing became common, notably the DEC PDP-11 that arrived at Bell, support for character data stuffed in memory words became important. The typeless nature of the language was seen as a disadvantage, which led Thompson and Ritchie to develop an expanded version of the langua ...

Mazda MX-5 (NB)
The Mazda MX-5 (NB) is the second generation of the Mazda MX-5 manufactured from 1998 until 2005. The model continued the MX-5's philosophy of being a lightweight, front mid-engine, rear-wheel-drive roadster while featuring numerous performance improvements, however lacking its predecessor's retractable headlamps. The NB is also the only generation to feature a factory-built turbocharged variant in the form of the Mazdaspeed MX-5. Overview The redesigned MX-5 was previewed at the Tokyo Motor Show in October 1997. In February 1998, Mazda released the second-generation MX-5, production code NB, for the 1999 model year. The NB featured a more powerful engine and external styling cues borrowed from the third generation Mazda RX-7, designed in 1995 by Tom Matano. Prices in the United States, the main market for the MX-5, started at US$19,770. Although many parts of the interior and body were different, the most notable changes were the headlamps: the first generation's retracta ...

Nanobarn
A barn (symbol: b) is a metric unit of area equal to (100 fm2). Originally used in nuclear physics for expressing the cross sectional area of nuclei and nuclear reactions, today it is also used in all fields of high-energy physics to express the cross sections of any scattering process, and is best understood as a measure of the probability of interaction between small particles. A barn is approximately the cross-sectional area of a uranium nucleus. The barn is also the unit of area used in nuclear quadrupole resonance and nuclear magnetic resonance to quantify the interaction of a nucleus with an electric field gradient. While the barn never was an SI unit, the SI standards body acknowledged it in the 8th SI Brochure (superseded in 2019) due to its use in particle physics. Etymology During Manhattan Project research on the atomic bomb during World War II, American physicists at Purdue University needed a secretive name for a unit with which to quantify the cross-sectio ...

Nominal Bore
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. "Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a outside diameter). Specific pipe is identified by pipe diameter and another non-dimensional number for wall thickness referred to as the Schedule (Sched. or Sch., for example – "2-inch diameter pipe, Schedule 40"). NPS is often incorrectly called National Pipe Size, due to confusion with the American standard for pipe threads, " national pipe straight", which also abbreviates as "NPS". The European and international designation equivalent to NPS is ''DN'' (''diamètre nominal''/nominal diameter/Nennweite), in which sizes are measured in millimetres, see ISO 6708.

Neuroblastoma
Neuroblastoma (NB) is a type of cancer that forms in certain types of nerve tissue. It most frequently starts from one of the adrenal glands but can also develop in the neck, chest, abdomen, or spine. Symptoms may include bone pain, a lump in the abdomen, neck, or chest, or a painless bluish lump under the skin. Typically, neuroblastoma occurs due to a genetic mutation occurring during early development. Rarely, it may be due to a mutation inherited from a person's parents. Environmental factors have not been found to be involved. Diagnosis is based on a tissue biopsy. Occasionally, it may be found in a baby by ultrasound during pregnancy. At diagnosis, the cancer has usually already spread. The cancer is divided into low-, intermediate-, and high-risk groups based on a child's age, cancer stage, and what the cancer looks like. Treatment and outcomes depends on the risk group a person is in. Treatments may include observation, surgery, radiation, chemotherapy, or stem cell t ...

Naive Bayes Classifier
In statistics, naive Bayes classifiers are a family of simple "probabilistic classifiers" based on applying Bayes' theorem with strong (naive) independence assumptions between the features (see Bayes classifier). They are among the simplest Bayesian network models, but coupled with kernel density estimation, they can achieve high accuracy levels. Naive Bayes classifiers are highly scalable, requiring a number of parameters linear in the number of variables (features/predictors) in a learning problem. Maximum-likelihood training can be done by evaluating a closed-form expression, which takes linear time, rather than by expensive iterative approximation as used for many other types of classifiers. In the statistics literature, naive Bayes models are known under a variety of names, including simple Bayes and independence Bayes. All these names reference the use of Bayes' theorem in the classifier's decision rule, but naive Bayes is not (necessarily) a Bayesian method. Introductio ...

Boeing NB
__NOTOC__ The Boeing NB (or Model 21) was a primary training aircraft developed for the United States Navy in 1923. It was a two-bay, equal-span biplane of conventional configuration with interchangeable wheeled and float undercarriage. The pilot and instructor sat in tandem, open cockpits. The NBs were produced in two batches; the first (NB-1) were powered by radial engines and the second by war-surplus V-8s still in the Navy's inventory. The original prototype evaluated by the Navy had been assessed as being too easy to fly, and therefore of limited use as a trainer. In particular, it was noted that the aircraft was impossible to spin. The NB-1 design attempted to introduce some instability, but it was soon discovered that while it was now possible to get the aircraft into a spin, it was virtually impossible to recover from one. A series of modifications were made to attempt a compromise. Variants * VNB-1 - prototype (one built) * NB-1 - original production machine with Law ...

Niobium
Niobium is a chemical element with chemical symbol Nb (formerly columbium, Cb) and atomic number 41. It is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to pure titanium, and it has similar ductility to iron. Niobium oxidizes in Earth's atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel. Niobium is often found in the minerals pyrochlore and columbite, hence the former name "columbium". Its name comes from Greek mythology: Niobe, daughter of Tantalus, the namesake of tantalum. The name reflects the great similarity between the two elements in their physical and chemical properties, which makes them difficult to distinguish. English chemist Charles Hatchett reported a new element similar to tantalum in 1801 and named it columbium. In 1809, English chemist William Hyde Wollaston wrongly concluded that tantalum and columbium were identical. German chemist Heinrich Rose determin ...
