<P0-S0> The Queen Elisabeth Medical Foundation (QEMF) is a Belgian non-profit organization, founded in 1926 by Elisabeth of Bavaria, wife of Albert I. <P0-S1> She founded the organization, based on her experience with the wounded from the front-line during the First World War. <P0-S2> The foundation wants to encourage laboratory research and contacts between researchers and clinical practitioners, with a particular focus on neurosciences. <P0-S3> The QEMF supports seventeen university teams throughout Belgium. <SEP> <P1-S0> the story focuses on a family of anthropomorphic rabbits. <P1-S1> the widowed mother rabbit cautions her young against entering the vegetable garden of a man named mr. mcgregor, telling them: ``your father had an accident there; he was put in a pie by mrs. mcgregor ''. <P1-S2> her three daughters obediently refrain from entering the garden, going down the lane to pick blackberries, but her rebellious son peter enters the garden to snack on some vegetables. <P1-S3> peter ends up eating more than is good for him and goes looking for parsley to cure his stomach ache. <P1-S4> peter is spotted by mr. mcgregor and loses his jacket and shoes while trying to escape. <P1-S5> he hides in a watering can in a shed, but then has to run away again when mr. mcgregor finds him, and ends up completely lost. <P1-S6> after sneaking past a cat, peter sees the gate where he entered the garden from a distance and heads for it, despite being spotted and chased by mr. mcgregor again. <P1-S7> with difficulty he wriggles under the gate, and escapes from the garden, but he spots his abandoned clothing being used to dress mr. mcgregor's scarecrow. <P1-S8> after returning home, a sick peter is sent to bed by his mother, while his well - behaved sisters receive a sumptuous dinner of milk and berries as opposed to peter's supper of chamomile tea. <SEP> <P2-S0> Peter Delorge (born 19 April 1980 in Sint-Truiden, Belgium) is a professional football (soccer) midfielder, who spent his whole career at Sint-Truidense. <P2-S1> His position was in the defensive part of the midfield. <SEP> <P3-S0> stefan nystrom was a long-time resident of australia who was deported to sweden in 2006. he won a landmark decision at the united nations in 2011, establishing that non-citizens may also have the right to enter a country. <SEP> <P4-S0> On 3 May 1915 Italy officially revoked the Triple Alliance. <P4-S1> In the following days Giolitti and the neutralist majority of the Parliament opposed declaring war, while nationalist crowds demonstrated in public areas for it. <P4-S2> (The nationalist poet Gabriele D'Annunzio called this period le radiose giornate di Maggio -- ``the sunny days of May ''). <P4-S3> Giolitti had the support of the majority of Italian parliament so on 13 May Salandra offered his resignation to King Victor Emmanuel III, but then Giolitti learned that the London Pact was already signed: fearful of a conflict between the Crown and the Parliament and the consequences on both internal stability and foreign relationships, Giolitti accepted the fait accompli, declined to succeed as prime minister and Salandra's resignation was not accepted. <P4-S4> On 23 May, Italy declared war on Austria - Hungary. <P4-S5> This was followed by declarations of war on the Ottoman Empire (21 August 1915, following an ultimatum of 3 August), Bulgaria (19 October 1915) and the German Empire (28 August 1916).
