Age standardized rates (ASRs) and average age of incidence (AAI) values were determined for 12 different cancers, separately for males and females. Annual trends were analyzed using linear regression slopes. Absolute values were compared by two-tailed t-tests. The order of prevalence for incidences of male (M) cancers were: lung, skin, colorectal, prostate, brain, bladder, liver and stomach. Similarly, for females (F) they were: breast, gynaecological, skin, colorectal, lung, liver, brain, stomach and bladder. The following cancer cases were more common than in SE and NE: lung (M) and skin (both genders). Breast (F), prostate, stomach (F), bladder (both sexes), cervix and corpus were less frequent; the rest were comparable. There was no difference in the annual trend...

It is shown that quasi-periodic motions (on a torus) bifurcate from a periodic motion, and there exists a shift in the critical value of the parameter compared to that of the associated autonomous system which was studied earlier. The solutions and their

It is shown that these equations can be constructed by making use of a given a priori set of invo- lutive invariants and proved that their solutions in the Hamilton-Jacobi separable variable case give rise to the integral submanifold imbedding mapping, which is known to be a main ingredient for Liouville-Arnold integrability by quadratures of the Hamiltonian system under consideration.

The application to the non-standard Hamiltonian analysis of the Maxwell and Yang-Mills type dynamical systems is presented. A symplectic reduction theory of the classical Maxwell electromagnetic field equations is formulated, the important Lorentz condition, ensuring the existence of electromagnetic waves [5, 6], is naturally included into the Hamiltonian picture, thereby solving the well known Dirac, Fock and Podolsky problem [10]. The symplectically reduced Poissonian structures and the related classical minimal interaction principle, concerning the Yang-Mills type equations, are considered.

The magic properties of the second quantization method, invented by Fock in 1934, are demonstrated, and an impressive application to the theory of nonlinear dynamical systems is considered. Von Neumann first applied the spectral theory of self-adjoint operators on Hilbert spaces to explain the radiation spectra of atoms and the related matter stability [2] (1926); Fock was the first to introduce the notion of many-particle Hilbert space, named a Fock space, and introduced related creation and annihilation operators acting on it [3] (1932); Weyl understood the fundamental role of the notion of symmetry in physics and developed a physics-oriented group theory; moreover, he showed the importance of different representations of classical matrix groups for physics and studied unitary representations of the Heisenberg-Weyl group related to creation and annihilation operators on a Fock space [4] (1931). At the end of the 20th century, new developments were due to Faddeev with co-workers (quantum inverse spectral theory transform [5], 1978); Drinfeld, Donaldson, and Witten (quantum groups and algebras, quantum topology, and quantum superanalysis [6-8], 1982-1994);

This scheme appeared to be very useful when proving the Liouville integrability of many finite-dimensional systems such as Kowalevskaya's top [5], Neumann-type systems [6, 7], etc. Below, we study the problem of the complete integrability of nonlinear oscillatory dynamical systems connected, in particular, both with the Cartan decomposition of a Lie algebra G = K P, where K is the Lie algebra of a fixed subgroup K ⊂ G with respect to an involution σ : G → G on the Lie group G, and with a Poisson action of special type on a symplectic matrix manifold. 2.
