The R-36 () is a family of intercontinental ballistic missiles (ICBMs) and space launch vehicles designed by the Soviet Union during the Cold War. The original R-36 was produced under the Soviet industry designation 8K67 and was given the NATO reporting name SS-9 Scarp. The later version, the R-36M was produced under the GRAU designations 15A14 and 15A18 and was given the NATO reporting name SS-18 Satan. This missile was viewed by certain U.S. analysts as giving the Soviet Union first strike advantage over the U.S., particularly because of its very heavy throw weight and extremely large...
The Lotka–Volterra equations, also known as the predator–prey equations, are a pair of first-order, non-linear, differential equations frequently used to describe the dynamics of biological systems in which two species interact, one a predator and one its prey. They evolve in time according to the pair of equations:
:\frac{dx}{dt} = x(\alpha - \beta y)
:\frac{dy}{dt} = - y(\gamma - \delta x)
where,
*y is the number of some predator (for example, wolves);
*x is the number of its prey (for example, rabbits);
*\frac{dy}{dt} and \frac{dx}{dt} represent the growth of the two populatio...
Hen Wlad Fy Nhadau () is the national anthem of Wales. The title – taken from the first words of the song – means "Old Land of My Fathers", usually rendered in English as simply "Land of My Fathers". The words were written by Evan James and the tune composed by his son, James James, both residents of Pontypridd, Glamorgan, in January 1856. The earliest written copy survives and is part of the collections of the National Library of Wales.
Origins
Glan Rhondda (Banks of the Rhondda), as it was known when it was composed, was first performed in the vestry of the original Capel Tabor, Maest...
Lancelot, the Knight of the Cart () is an Old French poem by Chrétien de Troyes. Chrétien probably composed the work (in the 1170s) at the same time as or slightly before writing Yvain, the Knight of the Lion, which refers to the action in Lancelot a number of times. The love affair between Guinevere and Lancelot appears for the first time in this poem as does Arthur's court city of Camelot.
Story
The action centers on Lancelot's rescue of the queen after she has been abducted by Meleagant, the son of Bademagu. The Abduction of Guinevere is one of the oldest motifs in Arthurian legend...
The Romance languages (sometimes referred to as Romanic languages, Latin languages, Neolatin languages or Neo-Latin languages) are a branch of the Indo-European language family, more precisely of the Italic languages subfamily, comprising all the languages that descend from Vulgar Latin, the language of ancient Rome. There are more than 800 million native speakers worldwide, mainly in the Americas and Europe, as well as many smaller regions scattered throughout the world. Because of the extreme difficulty and varying methodology of distinguishing among language, variety, and dialect, it ...
Le roman ou gallo-roman est une transition du latin populaire s'étant développée au début du Moyen Âge (Haut Moyen Âge).
Le terme roman, dérivé de l'adjectif latin romanus, s'applique aux langues issues de celle que parlaient les Romains, par opposition à celles qui ont été introduites plus tard, comme les langues germaniques.
Évolution
L'apparition du gallo-roman ne peut pas être datée avec précision. À la question « Quand a-t-on cessé de parler latin en Gaule ? », l'historien Ferdinand Lot répond « Jamais. » Il y a eu un glissement insensible du latin classique au bas-latin popul...
The Gallo-Romance branch of Romance languages include French and the other langue d'oïl dialects, Occitan (langue d'oc), Franco-Provençal and other languages (sociolects).
Other possible classifications
Some specialists add Catalan language and it is sometimes classified together with Occitan inside an Occitano-Romance subgroup too.
Traditional geographical extension
They are spoken in France (except Corsica, West Britanny, French Basque country, Westhoek French Flanders, Alsace and a part of Lorraine, that had other original languages), a part of Belgium speaks traditionally two d...
On nomme langues romanes les langues issues essentiellement du latin vulgaire (au sens étymologique de « populaire »), c'est-à-dire la forme de latin vernaculaire utilisée pour la communication de tous les jours, ainsi que des langues indigènes, dont le celtique continental.
Ces langues ont été parlées ou le sont encore dans un ensemble géographique désigné par le terme de Romania, désignant le Nord-Ouest européen de l'ancien Empire romain d'Occident et l'Empire Romain d'Orient, où les Valaques parlaient latin (mais où la langue grecque est rapidement devenue officielle en Europe et en...
