[Q]: Academic higher education in Estonia is divided into three levels: bachelor's, master's, and doctoral studies. In some specialties (basic medical studies, veterinary, pharmacy, dentistry, architect-engineer, and a classroom teacher programme) the bachelor's and master's levels are integrated into one unit. Estonian public universities have significantly more autonomy than applied higher education institutions. In addition to organising the academic life of the university, universities can create new curricula, establish admission terms and conditions, approve the budget, approve the development plan, elect the rector, and make restricted decisions in matters concerning assets. Estonia has a moderate number of public and private universities. The largest public universities are the University of Tartu, Tallinn University of Technology, Tallinn University, Estonian University of Life Sciences, Estonian Academy of Arts; the largest private university is Estonian Business School.
[A]: What are the three levels of higher learning in Estonia?


[Q]: After 1870, the new railroads across the Plains brought hunters who killed off almost all the bison for their hides. The railroads offered attractive packages of land and transportation to European farmers, who rushed to settle the land. They (and Americans as well) also took advantage of the homestead laws to obtain free farms. Land speculators and local boosters identified many potential towns, and those reached by the railroad had a chance, while the others became ghost towns. In Kansas, for example, nearly 5000 towns were mapped out, but by 1970 only 617 were actually operating. In the mid-20th century, closeness to an interstate exchange determined whether a town would flourish or struggle for business.
[A]: after about what year did railroads bring hunters to the great plains?


[Q]: Aspirin is an appropriate immediate treatment for a suspected MI. Nitroglycerin or opioids may be used to help with chest pain; however, they do not improve overall outcomes. Supplemental oxygen should be used in those with low oxygen levels or shortness of breath. In ST elevation MIs treatments which attempt to restore blood flow to the heart are typically recommended and include angioplasty, where the arteries are pushed open, or thrombolysis, where the blockage is removed using medications. People who have a non-ST elevation myocardial infarction (NSTEMI) are often managed with the blood thinner heparin, with the additional use angioplasty in those at high risk. In people with blockages of multiple coronary arteries and diabetes, bypass surgery (CABG) may be recommended rather than angioplasty. After an MI, lifestyle modifications, along with long term treatment with aspirin, beta blockers, and statins, are typically recommended.
[A]:
What can be used for immediate treatment for MI?
