Question: The Bologna process has been adopted, since 2006, by Portuguese universities and poly-technical institutes. Higher education in state-run educational establishments is provided on a competitive basis, a system of numerus clausus is enforced through a national database on student admissions. However, every higher education institution offers also a number of additional vacant places through other extraordinary admission processes for sportsmen, mature applicants (over 23 years old), international students, foreign students from the Lusosphere, degree owners from other institutions, students from other institutions (academic transfer), former students (readmission), and course change, which are subject to specific standards and regulations set by each institution or course department. Most student costs are supported with public money. However, with the increasing tuition fees a student has to pay to attend a Portuguese state-run higher education institution and the attraction of new types of students (many as part-time students or in evening classes) like employees, businessmen, parents, and pensioners, many departments make a substantial profit from every additional student enrolled in courses, with benefits for the college or university's gross tuition revenue and without loss of educational quality (teacher per student, computer per student, classroom size per student, etc.).
Is there an answer to this question: When was the Bologna process adopted?

Answer: 2006


Question: The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders. Moving to Hammondsport, the group then designed and built the Red Wing, framed in bamboo and covered in red silk and powered by a small air-cooled engine. On March 12, 1908, over Keuka Lake, the biplane lifted off on the first public flight in North America.[N 24] [N 25] The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). One of the AEA's inventions, a practical wingtip form of the aileron, was to become a standard component on all aircraft. [N 26] The White Wing and June Bug were to follow and by the end of 1908, over 150 flights without mishap had been accomplished. However, the AEA had depleted its initial reserves and only a $15,000 grant from Mrs. Bell allowed it to continue with experiments. Lt. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer, Virginia, on September 17, 1908.
Is there an answer to this question: What did the AEA work on after kites?

Answer:
gliders
