Public College Enrollment in Minnesota's Changing Population Pattern 1970-85.

Statewide trends from 1970 to 1985 in the number of high school graduates, college age population, and enrollment in colleges or vocational schools are examined along with the geographical variations across the state. These data are used to project enrollment figures for public colleges in 1975, 1980, and 1985

Thermodynamics of SU(N) Yang-Mills theories in 2+1 dimensions II - The deconfined phase

We present a non-perturbative study of the equation of state in the deconfined phase of Yang-Mills theories in D=2+1 dimensions. We introduce a holographic model, based on the improved holographic QCD model, from which we derive a non-trivial relation between the order of the deconfinement phase transition and the behavior of the trace of the energy-momentum tensor as a function of the temperature T. We compare the theoretical predictions of this holographic model with a new set of high-precision numerical results from lattice simulations of SU(N) theories with N=2, 3, 4, 5 and 6 colors. The latter reveal that, similarly to the D=3+1 case, the bulk equilibrium thermodynamic quantities (pressure, trace of the energy-momentum tensor, energy density and entropy density) exhibit nearly perfect proportionality to the number of gluons, and can be successfully compared with the holographic predictions in a broad range of temperatures. Finally, we also show that, again similarly to the D=3+1 case, the trace of the energy-momentum tensor appears to be proportional to T^2 in a wide temperature range, starting from approximately 1.2 T_c, where T_c denotes the critical deconfinement temperature.Comment: 2+36 pages, 10 figures; v2: comments added, curves showing the holographic predictions included in the plots of the pressure and energy and entropy densities, typos corrected: version published in JHE

Improved Holographic QCD

We provide a review to holographic models based on Einstein-dilaton gravity with a potential in 5 dimensions. Such theories, for a judicious choice of potential are very close to the physics of large-N YM theory both at zero and finite temperature. The zero temperature glueball spectra as well as their finite temperature thermodynamic functions compare well with lattice data. The model can be used to calculate transport coefficients, like bulk viscosity, the drag force and jet quenching parameters, relevant for the physics of the Quark-Gluon Plasma.Comment: LatEX, 65 pages, 28 figures, 9 Tables.

Kaivosmiehistä maanviljelijöihin: Suomalaiset siirtolaiset pohjoisten suurten järvien alueella Yhdysvalloissa

Niin absoluuttisesti kuin relatiivisesti mitattuna suomalaisten muutto Amerikkaan 1800-luvun ja 1900-luvun alun aikana ei saavuttanut sellaisia mittasuhteita kuin monissa muissa Euroopan maissa. Arvioiden mukaan vuosien 1864 ja 1914 välisenä aikana Amerikkaan muutti yli 300 000 suomalaista (Kero 1974). Sen sijaan esimerkiksi Saksasta lähti 5 880 000 siirtolaista, Italiasta 4 630 000, Irlannista 4 555 000 ja Ruotsista 1 210 000 (U.S. Department of Labor 1929). Jopa Norjasta, jonka väkiluku oli hieman pienempi kuin Suomen, siirtolaisia lähti yli kaksinkertainen määrä eli 696 000 (Qualey 1938)
