The Contra Dam, commonly known as the Verzasca Dam and the Locarno Dam, is an arch dam on the Verzasca River in the "Val Verzasca" of Ticino, Switzerland.
 The dam creates Lago di Vogorno 2 km upstream of Lake Maggiore and supports the 105 MW Verzasca Hydroelectric Power Station hydroelectric power station.
 It was constructed between 1961 and 1965 and starting shortly after its reservoir was filled, a series of earthquakes related to its water load occurred until 1971.
 The dam is owned and operated by Verzasca SA and is the fourth tallest in Switzerland.
Emilia is a character in the tragedy "Othello" by William Shakespeare.
 The character's origin is traced to the 1565 tale, "Un capitano Moro" from Giovanni Battista Giraldi Cinthio's "Gli Hecatommithi".
 There, the character is described as young and virtuous, is referred to simply as the ensign's wife, and becomes Desdemona's companion in Cyprus.
 In Shakespeare, she is named Emilia, is the wife of Othello's ensign, Iago, and is an attendant to Othello's wife, Desdemona.
 While considered a minor character in the drama, she has been portrayed by several notable actresses on film, with Joyce Redman receiving an Academy Award nomination for her performance.
Bobosaurus is an extinct genus of sauropterygian reptile related to plesiosaurs.
 It is based on the holotype MFSN 27285, a partial skeleton found in Early Carnian-age rocks (early Late Triassic) of the Rio del Lago Formation, northeastern Italy.
 "Bobosaurus" was named in 2006 by Fabio M. Dalla Vecchia and the type species is "B. forojuliensis".
 It may be a pistosaurid, or closer to Plesiosauria.
 A recent cladistic analysis found it to be a pistosaur.
