Query: Nonperturbative QCD: confinement and deconfinement   After a short exposition of field correlators in the QCD vacuum and the
recently discovered Casimir scaling phenomenon, the origin of confinement in
QCD is discussed and two possible mechanisms are suggested, which can be
checked by new lattice measurements. Screening of confinement due to sea quarks
is discussed and quantitatively explained. Deconfinement is introduced via the
colorelectric field evaporation and the transition temperature Tc is found
numerically in good agreement with lattice measurements. The Tc dependence on
Nc and nf is also predicted and agrees with the recent lattice data.
