The Svalbard Global Seed Vault ( Norwegian: Svalbard globale frøhvelv) is a secure backup facility for the world's crop diversity on the Norwegian island of Spitsbergen in the remote Arctic Svalbard archipelago. [ 5] The Seed Vault provides long-term storage of duplicates of seeds conserved in genebanks around the world.
Detonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which must always be specified, and may be too low if the test charge diameter is not large enough. Especially for little studied explosives there may be ...
Fibonacci sequence. In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes ...
9,900 m (32,500 ft) maximum ceiling. Sights. ZF.20. The 8.8 cm Flak 18/36/37/41 is a German 88 mm anti-aircraft and anti-tank artillery gun, developed in the 1930s. It was widely used by Germany throughout World War II and is one of the most recognized German weapons of the conflict. The gun was universally known as the Acht-acht ("eight-eight ...
Beans: In pulp, in skin, and naked. Roasted nibs (pieces of kernels) are generally powdered and melted into chocolate liquor, but also inserted into chocolate bars to give additional "crunch". The cocoa bean, also known simply as cocoa ( / ˈkoʊ.koʊ /) or cacao ( / kəˈkaʊ / ), [ 1] is the dried and fully fermented seed of Theobroma cacao ...
Description. Close-up of flowers of Phyteuma orbiculare. Phyteuma orbiculare reaches on average 20–50 centimetres (7.9–19.7 in) of height. A deep blue, almost purple wildflower that is not as it seems: each head, rather than being a single bloom, is actually a collection of smaller ones, huddled together. [2]
The hypothesis of dark matter has an elaborate history. [18] [19] In the appendices of the book Baltimore lectures on molecular dynamics and the wave theory of light where the main text was based on a series of lectures given in 1884, [18] Lord Kelvin discussed the potential number of stars around the Sun from the observed velocity dispersion of the stars near the Sun, assuming that the Sun ...
A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae ). Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower. These petals attract pollinators, and reproductive organs that produce gametophytes, which in ...
