In recent paper Fakkousy et al. show that the 3D Hénon-Heiles system with Hamiltonian $$ H = \frac{1}{2} (p_1 ^2 + p_2 p_3 ^2) +\frac{1}{2} (A q_1 C q_2 B q_3 (\alpha \gamma ^2)q_3 \frac{\beta }{3}q_3 ^3 is integrable in sense of Liouville when $$\alpha , \frac{\alpha }{\beta } 1, A C$$ ; or \frac{1}{6}, B-arbitrary; \frac{1}{16}, C, \frac{A}{B} \frac{1}{16}$$ (and course, =\gamma =0$$ which ca...

As part of a comprehensive program of isolation and comparison of the various nucleoprotein frac tions of normal and leukemic mouse spleen (10, 11), the macromolecular particles of the cyto plasm have been separated by differential centrifugation and studied in the analytical ultracentrifuge. Although these preparations contain large amounts of polydisperse material, there are also several well...

Recently, we pointed out that on a class on non exactly decimable frac-tals two diierent parameters are required to describe diiusive and vibra-tional dynamics. This phenomenon we call dynamical dimension splitting is related to the lack of exact decimation invariance for these structures, which turn out to be invariant under a more complex cutting-decimation transform. In this paper we study i...

Orbital fractures commonly occur in maxillofacial trauma causing enophthalmos and diplopia. The isolated orbital fl oor fracture often called as blow out fracture is a common presentation following blunt trauma. The fl oor fractures may also occur in combination with zygomatic arch fractures, Le Fort II or III or with frac ture of other orbital bones. The cosmetic and functional problems can vi...

In the article the following concepts were introduced: the set of integers (Z) and its elements (integers), congruences (i1 ≡ i2(mod i3)), the ceiling and floor functors (dxe and bxc), also the fraction part of a real number (frac), the integer division (÷) and remainder of integer division (mod). The following schemes were also included: the separation scheme (SepInt), the schemes of integer i...
