The BRST approach is applied to the description of irreducible massless higher spins representations of the Poincare group
in arbitrary dimensions. The total system of constraints in such theory includes both the first and the second class constraints. The
corresponding nilpotent BRST charge contains terms up to the seventh degree in ghosts.

A modification of the harmonic superfield formalism in D=4, N=2 supergravity using a subsidiary condition of covariance
under the background supersymmetry with a central charge (B-covariance) is considered. Conservation of analyticity together
with the B-covariance leads to the appearance of linear gravitational superfields. Analytic prepotentials arise in a decomposition
of the background linear superfields in terms of spinor coordinates and transform in a nonstandard way under the background
supersymmetry. The linear gravitational superfields can be written via spinor derivatives of nonanalytic spinor prepotentials. The
perturbative expansion of supergravity action in terms of the B-covariant superfields and the corresponding version of the differential-geometric
formalism are considered. We discuss the dual harmonic representation of the linearized extended supergravity,
which corresponds to the dynamical condition of Grassmann analyticity.

In the world of infinitely small, the world of atoms, nuclei and particles, the quantum mechanics enforces its laws. The discovery
of Quanta, this unbelievable castration of the Possible in grains of matter and radiation, in discrete energy levels compels us
of thinking the Single to comprehend the Universal. Quantum Numbers, magic Numbers and Numbers sign the wave. The matter
is vibration. to describe the music of the world one needs keys, measures, notes, rules and partition: one needs quantum mechanics.
The particles reduce themselves not in material points as the scholars of the past centuries thought, but they must be conceived
throughout the space, in the accomplishment of shapes of volumes. When Einstein asked himself whether God plays dice, there
was no doubt among its contemporaries that if He exists He is a geometer. In a Nature reduced to Geometry, the symmetries assume
their role in servicing the Harmony. The symmetries allow ordering the energy levels to make them understandable. They impose
there geometrical rules to the matter waves, giving them properties which sometimes astonish us. Hidden symmetries, internal
symmetries and newly conceived symmetries have to be adopted subsequently to the observation of some order in this world of
Quanta. In turn, the symmetries provide new observables which open new spaces of observation.

The TNO Human Factors Research institute has developed and evaluated a model for designing and conducting technical
training (Structured Troubleshooting) aimed at enhancing the transfer of training to the situation on board. The question is whether
this model is applicable to the innovation of two functions for officers in the Weapon Engineering Branch: the Weapon Engineer-
