In the framework of stochastic QCD vacuum model we show that colour particle 
loss its colour propagating through QCD vacuum medium. At large distances 
colour disappear completely. 
 
 
Testing of quark-hadron duality via the Adler D-function

A key problem in making precise perturbative QCD predictions, which connects 
with the requirement of renormalization group invariance, is the uncertainty in 
fixing the renormalization scale. We study the scale dependence of fresh four-
loop QCD corrections to some processes both within the standard perturbative 
and singularity-free analytic perturbation theory. We demonstrate that within the 
analytic approach the results are practically renormalization scale independent 
and lead to rather different Q^2 evolution than the standard perturbative 
correction possesses.

In this talk we examine a geometric 2D-dynamics of Langmuir-Blodgett 
monolayer (LB-monolayer). To do it the vertical component of Berwald 
curvature tensor is calculated, and the Berwald-Lagrange flag curvature K is 
determined. A simulation is performed, and possible physical interpretations are 
also given. It was established that sign change of K from positive to negative 
occurs at the compressing. The dependence of (-K) on an area of monolayer 
behaves similar to an isotherm of compressing in the neighbourhood of phase 
transition. Convolution of the vertical component of Berwald curvature tensor -- 
Douglas tensor Bijkl with metric tensor was calculated. An anomalous behavior of 
the convolution is similar to a behavior of susceptibility at phase transition.
