Question: Energiprojekt AB is based in the country that participated in the 1920 Summer Olympics hosted by country A. When did Italy enter the same conflict as Albert I of country A?

<P0-S0> Sweden competed at the 1920 Summer Olympics in Antwerp, Belgium. <P0-S1> 260 competitors, 247 men and 13 women, took part in 100 events in 18 sports. <SEP> <P1-S0> On 3 May 1915 Italy officially revoked the Triple Alliance. <P1-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. <P1-S2> (The nationalist poet Gabriele D'Annunzio called this period le radiose giornate di Maggio -- ``the sunny days of May ''). <P1-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. <P1-S4> On 23 May, Italy declared war on Austria - Hungary. <P1-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). <SEP> <P2-S0> tug of war was contested as a team event in the summer olympics at every olympiad from 1900 to 1920. originally the competition was entered by groups called clubs. <P2-S1> a country could enter more than one club in the competition, making it possible for one country to earn multiple medals. <P2-S2> this happened in 1904, when the united states won all three medals, and in 1908 when the podium was occupied by three british teams. <P2-S3> sweden was also among the top countries with two medals, one as a member of the mixed team. <SEP> <P3-S0> The Queen Elisabeth Medical Foundation (QEMF) is a Belgian non-profit organization, founded in 1926 by Elisabeth of Bavaria, wife of Albert I. <P3-S1> She founded the organization, based on her experience with the wounded from the front-line during the First World War. <P3-S2> The foundation wants to encourage laboratory research and contacts between researchers and clinical practitioners, with a particular focus on neurosciences. <P3-S3> The QEMF supports seventeen university teams throughout Belgium. <SEP> <P4-S0> sport plays an important role in estonian culture. <P4-S1> after declaring independence from russia in 1918, estonia first competed as a nation at the 1920 summer olympics, although the national olympic committee was established in 1923. estonian athletes took part of the olympic games until the country was annexed by the soviet union in 1940. the 1980 summer olympics sailing regatta was held in the capital city tallinn. <P4-S2> after regaining independence in 1991, estonia has participated in all olympics. <P4-S3> estonia has won most of its medals in athletics, weightlifting, wrestling and cross-country skiing. <P4-S4> estonia has had very good success at the olympic games given the country's small population. <P4-S5> estonia's best results were being ranked 13th in the medal table at the 1936 summer olympics, and 12th at the 2006 winter olympics. <SEP> <P5-S0> Although the reciprocating steam engine is no longer in widespread commercial use, various companies are exploring or exploiting the potential of the engine as an alternative to internal combustion engines. <P5-S1> The company Energiprojekt AB in Sweden has made progress in using modern materials for harnessing the power of steam. <P5-S2> The efficiency of Energiprojekt's steam engine reaches some 27-30% on high-pressure engines. <P5-S3> It is a single-step, 5-cylinder engine (no compound) with superheated steam and consumes approx. <P5-S4> 4 kg (8.8 lb) of steam per kWh. <P5-S5> [not in citation given]
