Isle of the Dead is a 1945 horror film directed by Mark Robson and made for RKO Radio Pictures by producer Val Lewton. The film's script was inspired by the painting Isle of the Dead by Arnold Böcklin, which appears behind the title credits, though the film was originally titled Camilla during production. It was written by frequent Lewton collaborator Ardel Wray. It starred Boris Karloff. Isle of the Dead was the second of three films Lewton made with Karloff, and the fourth of five pictures Robson directed for Lewton. Plot An onscreen text warns of the superstitious belief in a vorvolaka, a malevolent force in human form. The film properly begins during the Balkan Wars of 1912. While his troops are burying their dead, General Pherides (Boris Karloff) and American reporter Oliver Davis (Marc Cramer) visit the Isle of the Dead to pay their respects to the General's long-dead wife. They discover the crypt despoiled; hearing a woman singing on the supposedly uninhabited island, they set out to find her. They also find retired Swiss archeologist Dr. Aubrecht (Jason Robards, Sr.), his Greek housekeeper...

Casein ( KAY-seen, from Latin caseus "cheese") is a family of related phosphoproteins (αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and Cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content.Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive. The most common form of casein is sodium caseinate. Casein is secreted into milk from mammary cells in the form of colloidal casein micelles, a type of biomolecular condensate. As a food source, casein supplies amino acids, carbohydrates, and two essential elements, calcium and phosphorus. Composition Casein contains a high number of proline amino acids which hinder the formation of common secondary structural motifs of proteins. There are also no disulfide bridges. As a result, it has relatively little tertiary structure. It is relatively hydrophobic...

The First Balkan War lasted from October 1912 to May 1913 and involved actions of the Balkan League (the Kingdoms of Bulgaria, Serbia, Greece and Montenegro) against the Ottoman Empire. The Balkan states' combined armies overcame the initially numerically inferior (significantly superior by the end of the conflict) and strategically disadvantaged Ottoman armies, achieving rapid success. The war was a comprehensive and unmitigated disaster for the Ottomans, who lost 83% of their European territories and 69% of their European population. As a result of the war, the League captured and partitioned almost all of the Ottoman Empire's remaining territories in Europe. Ensuing events also led to the creation of an independent Albania, which dissatisfied the Serbs. Bulgaria, meanwhile, was dissatisfied over the division of the spoils in Macedonia and attacked its former allies, Serbia and Greece, on 16 June 1913, which provoked the start of the Second Balkan War. During the war, many civilians, overwhelmingly Muslim Turks, were either killed or forced to flee their homes. The highly politicized and disorganized units of the Ottoman army...

In mathematics, a saddle point or minimax point 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. An example of a saddle point is when there is a critical point with a relative minimum along one axial direction (between peaks) and at a relative maximum along the crossing axis. However, a saddle point need not be in this form. For example, the function f ( x , y ) = x 2 + y 3 ...
