Expectations and Outcomes of Interregional IT Training for Teachers
The experience gained in performing the sequence of Joint European Projects sponsored by EU TEMPUS Program in the field of IT further education of teachers in Ukraine, Tajikistan and Uzbekistan is summarised. The international consortia headed by Leipzig University of Applied Sciences in-volves, besides partner country institutions, Universities from Germany, Swe-den, Italy, Poland and Slovak Republic. The consortia have been working as a well organized team successfully establishing a collaborative network for IT training. The Polish project Interkl@sa served as a sample for the project Inter- Collegia which was the first one in this package of school-oriented projects. Thereafter the network of schools patronised by the University of Kyiv-Mohyla Academy has been extended to comprise special schools for visually impaired students. Consequently the network went over borders involving further rather distant countries
Phase coexistance in polydisperse mixture of hard-sphere colloidal and flexible chain particles
A theoretical scheme for the calculation of the full phase diagram (including
cloud and shadow curves, binodals and distribution functions of the coexisting
phases) for colloid-polymer mixtures with polymer chain length polydispersity
and hard-sphere colloidal and polymeric monomer sizes polydispersity is
proposed. The scheme combines thermodynamic perturbation theory for associating
fluids and recently developed method used to determine the phase diagram of
polydisperse spherical shape colloidal fluids (L.Bellier-Castella {\it et al.},
{\it J.Chem.Phys.} {\bf 113}, 8337(2000)). By way of illustration we present
and discuss the full phase diagram for the mixture with polydispersity in the
size of the hard-sphere colloidal particles.Comment: 6 pages, 4 figure
Web Portal for Support of Joint European Projects
Our task was primary design and development of web-portal for Joint European Projects under aegis of European Commission. The portal should provide a friendly and clear access to any dedicated information and concrete JEP portals themselves. In other words, the task was to create a modern web-resource with all necessary information about Projects, Commission, consortia and partners; ability to add new Joint European Projects and their pages; eFolio for members; storage of materials(articles, files) and ability to add/modify them; news, calendar of events and so on
Self Consistent Molecular Field Theory for Packing in Classical Liquids
Building on a quasi-chemical formulation of solution theory, this paper
proposes a self consistent molecular field theory for packing problems in
classical liquids, and tests the theoretical predictions for the excess
chemical potential of the hard sphere fluid. Results are given for the self
consistent molecular fields obtained, and for the probabilities of occupancy of
a molecular observation volume. For this system, the excess chemical potential
predicted is as accurate as the most accurate prior theories, particularly the
scaled particle (Percus-Yevick compressibility) theory. It is argued that the
present approach is particularly simple, and should provide a basis for a
molecular-scale description of more complex solutions.Comment: 6 pages and 5 figure

Equilibrium phase behavior of polydisperse hard spheres
We calculate the phase behavior of hard spheres with size polydispersity,
using accurate free energy expressions for the fluid and solid phases. Cloud
and shadow curves, which determine the onset of phase coexistence, are found
exactly by the moment free energy method, but we also compute the complete
phase diagram, taking full account of fractionation effects. In contrast to
earlier, simplified treatments we find no point of equal concentration between
fluid and solid or re-entrant melting at higher densities. Rather, the fluid
cloud curve continues to the largest polydispersity that we study (14%); from
the equilibrium phase behavior a terminal polydispersity can thus only be
defined for the solid, where we find it to be around 7%. At sufficiently large
polydispersity, fractionation into several solid phases can occur, consistent
with previous approximate calculations; we find in addition that coexistence of
several solids with a fluid phase is also possible
Thermodynamically consistent Reference Interaction Site Model theory of the tangent diatomic fluid
Thermodynamic and structural properties of the tangent diatomic fluid are
studied in the framework provided by the Reference Interaction Site Model
(RISM) theory, coupled with a Modified Hypernetted Chain closure. The
enforcement of the internal thermodynamic consistency of the theory is
described in detail. The results we obtain almost quantitatively agree with
available or newly generated simulation data. We envisage the possibility to
extend the consistent RISM formalism to generic, more realistic molecular
fluids.Comment: Typeset with LaTeX, 6 pages, 3 figures (5 subfigures), 28 references,
