Helvella crispa is creamy white in colour, 6–13 centimetres (–5 inches) in length, with a cap 2–5 cm (1–2 in) in diameter. It is striking due to its irregularly shaped lobes on the cap, but with a robust creamy-white base (2–8×1–2.5 cm in size). Its flesh is thin and brittle. The stem is 3–10 cm (1¼–4 in) long, white or ...

Withdrawn. 1924–1962. Disposition. All scrapped. The Caledonian Railway 264 and 611 classes were 0-4-0 saddle tank locomotives designed by Dugald Drummond and built by Neilson and Company in 1885. [1][2] Later examples were built at St Rollox Works under the direction of John F. McIntosh in 1895, 1900, 1902 and 1908. [2][3][4]
Helvella lacunosa, known as the slate grey saddle or fluted black elfin saddle in North America, simply as the elfin saddle in Britain, is an ascomycete fungus of the family Helvellaceae. It is one of the most common species in the genus Helvella. [ 1 ] The mushroom is readily identified by its irregularly shaped grey cap, fluted stem, and ...
Saddle point. In mathematics, a saddle point or minimax point[1] is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function. [2] An example of a saddle point is when there is a critical point with a relative ...

The class became the standard British shunting locomotive during the Second World War, and production continued until 1964 at various locomotive manufacturers.
The method of steepest descent is a method to approximate a complex integral of the form for large , where and are analytic functions of . Because the integrand is analytic, the contour can be deformed into a new contour without changing the integral. In particular, one seeks a new contour on which the imaginary part, denoted , of is constant ...
R4-S was a special batch built for the Central Electricity Generating Board, with a loading gauge of 9 feet 10 inches (3.00 m) over the standard 10 feet 8.5 inches (3.264 m). Delivered in 1952 to Croydon Power Station "A", it was quickly transferred to the "B" unit. Here it joined 2013 and 2104.
