A general model of generalized thermoelasticity with
temperaturedependent modulus of elasticity

A new formula of generalized thermoelasticity equations
for isotropic media is established. The present model does apply
to generalizations, the LordShulman theory with one relaxation
time and the GreenLindsay theory with two relaxation times, as
well as to the coupled theory. The normal mode analysis is used to
obtain the exact expressions for the temperature distribution,
thermal stresses, and the displacement components. The resulting
formulation is applied to three different concrete problems. The
first one deals with a thick plate subject to heating on parts of
the upper and lower surfaces of the plate; the second one concerns
the case of a heated punch moving across the surface of a
semiinfinite thermoelastic halfspace subject to appropriate
boundary conditions; and the third problem deals with a plate with
thermoinsulated surfaces subjected to timedependent compression.
Numerical results are given and illustrated graphically for the
problem considered. A comparison was made with the results
obtained in the case of temperatureindependent modulus of
elasticity in each theory.

 S. Piekarski:
On the thermodiffusion equation for electrically
charged matter

In this paper, we propose the thermodiffusion equation
for electrically charged matter. It is a generalisation of the
modified Fick law, which has been introduced in the paper:
S. Piekarski, "On the modified Fick law and its potential
applications" (J. Tech. Phys., 44, 2, 125131, 2003).
In the modified Fick law there exists a potential force acting on
the diffusing matter which is described as the gradient of the
potential U(x). Now we replace U(x)
by U(x)  qφ(x,t) where φ
is the electrostatic potential, while q is the electric charge
of a diffusing carrier. We write the corresponding field equations
and consider the electromotive force induced by the temperature
gradient. It is easy to compute this force under the assumption
that the system is quasineutral. However, it seems that a more
realistic model of the electromotive force induced by the
temperature gradient should allow a deviation from
quasineutrality. Both versions are compared and it is interesting
whether the resulting expressions can be verified experimentally.

Li^{+} ionic conductivity calculations of solid electrolytes
on polymeric basis

This paper presents a theoretical approach to Li^{+}
ions diffusion in polymeric solid electrolytes. The following
parameters were calculated and then compared with the experimental
results: the mobility of lithium ions, diffusion coefficient and
recombination probability. Ionic conductivity of the electrolyte
was also calculated.

Anomalous movement resistance in a spinning gyroscope

A symmetric harnessed gyroscope accelerated to a given
spinning frequency takes different time periods to stop, depending
on the direction of previous spins. For repeated alternating,
anticlockwise and clockwise spinning, the rotation period in both
directions significantly increases, which is not the case when the
gyroscope is repeatedly rotated in the same direction. Using the
measurements it was observed, that the time of gyroscope's
rotation was significantly lengthened or shortened, what indicates
that it either increased or decreased the movement resistance of
the gyroscope. The presented experimental results suggest the
existence of anomalous movement resistance and demonstrate that a
fixed spinning gyroscope displays unusual historydependent
movement resistance effects. The effect is real, large,
reproducible and does not follow from experimental errors.

Key words: spinning gyroscope, movement resistance,
clockwise rotation, anticlockwise rotation.

The status of quantum information transfer at
the individual level

Two feasible energycorrelation experiments with twin
photons from parametric downconversion are proposed. A new method
to determine the lower bound of quantum information transfer speed
is proposed in the first experiment. Classical information
transfer exclusively by means of the quantum channel is the
expected result of the second experiment.
