Input: Question: When was the university that Nicolae Bagdasar graduated from in 1922 established? Passage 1:Olubowale Victor Akintimehin was born on September 21, 1984, in Northwest, Washington, D.C.. His parents were both from the Yoruba ethnic group of southwestern Nigeria, and both of them came from Austria to the United States in 1979. Wale's family first lived in Northwest, Washington, D.C. and then moved to Montgomery County, when Wale was at the age of 10. In 2002, he graduated from the Quince Orchard High School in Gaithersburg, Maryland, and moved to Largo, Maryland in Prince George's County. Wale attended Robert Morris University and Virginia State University on football scholarships, then transferred to Bowie State University. However, he dropped out due to academic reasons. Wale's love of the game of football and the Washington Redskins has led to a longstanding rumor that Wale had a tattoo of tight end Chris Cooley. He's also the cousin of an actor Gbenga Akinnagbe, who is best known as for playing Chris Partlow on HBO's The Wire. Wale's first recorded track, called "Rhyme of the Century", became his first song to ever be played on the local radio. In 2006, he was featured in the "Unsigned Hype" column of The Source magazine, and later signed to a local label, Studio 43. The track, called "Dig Dug (Shake It)" became popular in Washington, D.C., Maryland and Virginia, and was a tribute to Ronald "Dig Dug" Dixon, who was a percussion player for the go-go band Northeast Groovers. The song became the most requested song by a local artist in Washington D.C. radio history and Wale was the first local artist to get some BDS spins since DJ Kool in the early 1990s. The song was included in Wale's first mixtape, Paint a Picture.
 Passage 2:The Bofors 37 mm anti-tank gun was an anti-tank gun designed by Swedish manufacturer Bofors in the early 1930s originally for Swedish use. It was exported to several countries during the 1930's of which several bought licences to produce it themselves. The gun was used in several conflicts but most of its fame comes from its use in the Spanish civil war and the Winter war where it was used very successfully against light tanks and armored cars among other targets. Beyond its use as an infantry gun it was also used as the main armament in several armored cars and tanks such as the Dutch M39 Pantserwagen and the Polish 7TP to name a few. As the armor of tanks was increased during World War II the gun very quickly became obsolete as an anti-tank gun but was still used effectively as an infantry support gun for the entirety of the war, and well into the Cold War. This was due to its high fire rate, great mobility and effective high explosive shells.
 Passage 3:In October 1916, shortly after Romania entered World War I, he began studying at the reserve officers' school in Botoșani. From spring 1917 to March 1918, he fought on the front as a student master sergeant. He later recalled his wartime experiences in Amintiri. Notații autobiografice, pointing out the absurdity and uselessness of many of the army's actions. He found that officers, rather than judging based on circumstances, hid behind regulations, and that the troops' activities were subject to little real oversight. In October 1918, near the war's end, he enrolled in the literature and philosophy faculty of Bucharest University, graduating in 1922. Initially intending to study sociology, he changed his mind when he found that his professor Ion A. Rădulescu-Pogoneanu did not know the material. Bagdasar then opted for the history of philosophy, taught by a youthful Mircea Florian, whom he found erudite. While a student, he was an editor for Gazeta Transilvaniei, a newspaper based in Brașov, in the newly acquired Transylvania region. Following graduation and with the help of Mihai Popovici, he earned a scholarship at the University of Berlin, where he studied from 1922 to 1926. At Berlin, he took courses with Carl Stumpf, Heinrich Maier and Max Dessoir, and was active in the Kant-Gesellschaft society. He also acquired a solid grounding in Kantianism. He took his doctorate in 1926; it was titled Der Begriff des theoretischen Wertes bei Rickert ("The Notion of Theoretical Value in Rickert").
