Eöl, called the Dark Elf, is a fictional character in J. R. R. Tolkien's Middle-earth legendarium. He is introduced in The Silmarillion as an Elf of Beleriand and is a character existing in some form from the earliest to the latest writings.
Eöl, the Dark Elf, was a Sinda and lord of the forest of Nan Elmoth, a fief, north-east of Doriath. Even before he encountered the Dwarves of the Blue Mountains in Eriador, he had close relationships with other Dwarves, whom he met (and learned much forging skills from) along his travel through Middle-earth. When he entered the lands of Beleriand, the Sindar from Doriath recognised Eöl's kinship, and accepted him fairly quickly among the high court of Menegroth, due to his skills.
He was vassal of the High-king of Beleriand, Thingol. Before the wars began he lived in Doriath. When Melian enclosed it with her magic Girdle of Melian to aid its defence he became uneasy and moved to Nan Elmoth outside the Girdle. One of the greatest Elven-smiths of Middle-earth, he forged Anglachel and Anguirel two great, black, magic swords. Made from a meteorite's metal, they can cut all earth-delved iron and have an entrapped sentience. His smithwork rivalled that of the greatest of the Elven-smiths, Fëanor and Celebrimbor, in both fame and fate. One sword, Anglachel, he gave to Thingol as tribute for living in Nan Elmoth and it was eventually used by Túrin to slay Glaurung the dragon. The other sword, Anguirel, he kept for himself. Eöl devised galvorn, a black metal of great strength and malleability, which he fashioned into armour that he wore when he went abroad. He was friend of the Dwarves of Nogrod and Belegost and, until the founding of the realms of the Noldor, all the traffic of goods between the Sindar and Dwarves passed through Nan Elmoth.
In calculus of variations, the Euler–Lagrange equation, Euler's equation, or Lagrange's equation (although the latter name is ambiguous—see disambiguation page), is a second-order partial differential equation whose solutions are the functions for which a given functional is stationary. It was developed by Swiss-Russian mathematician Leonhard Euler and French-Italian mathematician Joseph-Louis Lagrange in the 1750s.
Because a differentiable functional is stationary at its local maxima and minima, the Euler–Lagrange equation is useful for solving optimization problems in which, given some functional, one seeks the function minimizing (or maximizing) it. This is analogous to Fermat's theorem in calculus, stating that at any point where a differentiable function attains a local extremum, its derivative is zero.
In Lagrangian mechanics, because of Hamilton's principle of stationary action, the evolution of a physical system is described by the solutions to the Euler–Lagrange equation for the action of the system. In classical mechanics, it is equivalent to Newton's laws of motion, but it has the advantage that it takes the same form in any system of generalized coordinates, and it is better suited to generalizations. In classical field theory there is an analogous equation to calculate the dynamics of a field.

This is an incomplete list of prominent characters from the Star Wars franchise, sorted by last name. Many of the characters listed below created for the original extended universe now called Legends. These are no longer are considered part of the Star Wars canon but remain on this list. While it's commonly considered that C-3PO and R2-D2 are the only Star Wars characters to be in all 7 movies, Obi-Wan Kenobi also appears in all of the films: during The Force Awakens, Ewan McGregor's voice can be heard saying the newly recorded dialogue "These are your first steps" while via archive recordings Alec Guinness says "Rey", both occur during a flashback caused by Rey's touching Anakin Skywalker's lightsaber. Before The Force Awakens, Anakin also appeared in all of the films, and was planned to make an appearance as a force ghost in The Force Awakens, but was removed in later versions of the story.
Please note that this table includes Special Edition changes such as Boba Fett in A New Hope or Ian McDiarmid replacing Clive Revill in The Empire Strikes Back. Also though David Prowse portrayed Darth Vader in the original trilogy, the character's voice was provided by James Earl Jones, and was replaced by Bob Anderson for the lightsaber duels in The Empire Strikes Back and Return of the Jedi
The Responsibility to Protect (R2P or RtoP) is a proposed norm that sovereignty is not an absolute right, and that states forfeit aspects of their sovereignty when they fail to protect their populations from mass atrocity crimes and human rights violations (namely genocide, crimes against humanity, war crimes, and ethnic cleansing).
While R2P is a proposed norm and not a law, its proponents maintain that it is based on a respect for the principles that underly international law, especially the underlying principles of law relating to sovereignty, peace and security, human rights, and armed conflict.
R2P provides a framework for using tools that already exist (i.e., mediation, early warning mechanisms, economic sanctions, and chapter VII powers) to prevent mass atrocities. Civil society organizations, states, regional organizations, and international institutions all have a role to play in the R2P process. The authority to employ the last resort and intervene militarily rests solely with United Nations Security Council (UNSC).
