Towards secure economic development : Russian-EU cooperation against organized crime and terrorism
This article is dedicated to the question of the development of the Russian-EU cooperation against organized crime and terrorism. The article examines the development of the Russian-EU relations, analyzes the EU-Russia Partnership and Cooperation Agreement at large and in the context of abovementioned spheres.
It analyzes the Agreement on cooperation between the European Police Office and the Russian Federation and the cooperation itself, based on this agreement.
Moreover, the article examines other forms of cooperation and the EU/Russia Road Map on the common space of freedom, security and justice. Finally, this article reveals the problems and perspectives of the Russian-EU cooperation in the fields of organized crime and terrorism.peer-reviewe
Universal Aspects of Coulomb Frustrated Phase Separation
We study the consequences of Coulomb interactions on a system undergoing a
putative first order phase transition. In two dimensions (2D), near the
critical density, the system is universally unstable to the formation of new
intermediate phases, which we call ``electronic microemulsion phases,'' which
consist of an intermediate scale mixture of regions of the two competing
phases. A correlary is that there can be no direct transition as a function of
density from a 2D Wigner crystal to a uniform electron liquid. In 3D, %we find
that if the strength of the Coulomb interactions exceeds a critical value, no
phase separation occurs, while for weaker Coulomb strength, electronic
microemulsions are inevitable. This tendency is considerably more pronounced in
anisotropic (quasi 2D or quasi 1D) systems, where a devil's staircase of
transitions is possible.Comment: 4 pg
Anisotropic dynamics of a vicinal surface under the meandering step instability
We investigate the nonlinear evolution of the Bales-Zangwill instability,
responsible for the meandering of atomic steps on a growing vicinal surface. We
develop an asymptotic method to derive, in the continuous limit, an evolution
equation for the two-dimensional step flow. The dynamics of the crystal surface
is greatly influenced by the anisotropy inherent to its geometry, and is
characterized by the coarsening of undulations along the step direction and by
the elastic relaxation in the mean slope direction. We demonstrate, using
similarity arguments, that the coalescence of meanders and the step flow follow
simple scaling laws, and deduce the exponents of the characteristic length
scales and height amplitude. The relevance of these results to experiments is
discussed.Comment: 10 pages, 7 figures; submitted to Phys. Rev.
Criteria for the observation of strong-field photoelectron holography
Photoelectron holography is studied experimentally and computationally using the ionization of ground-state xenon atoms by intense near-infrared radiation. A strong dependence of the occurrence of the holographic pattern on the laser wavelength and intensity is observed, and it is shown that the observation of the hologram requires that the ponderomotive energy Up is substantially larger than the photon energy. The holographic interference is therefore favored by longer wavelengths and higher laser intensities. Our results indicate that the tunneling regime is not a necessary condition for the observation of the holographic pattern, which can be observed under the conditions formally attributed to the multiphoton regime. © 2011 American Physical Society
Absence of the Transition into Abrikosov Vortex State of Two-Dimensional Type-II Superconductor with Weak Pinning
The resistive properties of thin amorphous NbO_{x} films with weak pinning
were investigated experimentally above and below the second critical field
H_{c2}. As opposed to bulk type II superconductors with weak pinning where a
sharp change of resistive properties at the transition into the Abrikosov state
is observed at H_{c4}, some percent below H_{c2} (V.A.Marchenko and
A.V.Nikulov, 1981), no qualitative change of resistive properties is observed
down to a very low magnetic field, H_{c4} < 0.006 H_{c2}, in thin films with
weak pinning. The smooth dependencies of the resistivity observed in these
films can be described by paraconductivity theory both above and below H_{c2}.
This means that the fluctuation superconducting state without phase coherence
remains appreciably below H_{c2} in the two-dimensional superconductor with
weak pinning. The difference the H_{c4}/H_{c2} values, i.e. position of the
transition into the Abrikosov state, in three- and two-dimensional
superconductors conforms to the Maki-Takayama result 1971 year according to
which the Abrikosov solution 1957 year is valid only for a superconductor with
finite dimensions. Because of the fluctuation this solution obtained in the
mean field approximation is not valid in a relatively narrow region below
H_{c2} for bulk superconductors with real dimensions and much below H_{c2} for
thin films with real dimensions. The superconducting state without phase
coherence should not be identified with the mythical vortex liquid because the
vortex, as a singularity in superconducting state with phase coherence, can not
exist without phase coherence.Comment: 4 pages, 4 figure
Stability of periodic domain structures in a two-dimensional dipolar model
We investigate the energetic ground states of a model two-phase system with
1/r^3 dipolar interactions in two dimensions. The model exhibits spontaneous
formation of two kinds of periodic domain structure. A striped domain structure
is stable near half filling, but as the area fraction is changed, a transition
to a hexagonal lattice of almost-circular droplets occurs. The stability of the
equilibrium striped domain structure against distortions of the boundary is
demonstrated, and the importance of hexagonal distortions of the droplets is
quantified. The relevance of the theory for physical surface systems with
elastic, electrostatic, or magnetostatic 1/r^3 interactions is discussed.Comment: Revtex (preprint style, 19 pages) + 4 postscript figures. A version

Дослідження функціонально-технологічних властивостей м’ясних січе-них напівфабрикатів з використанням рибної сировини
The article is devoted to the improvement of the recipes of minced meat products with using fish raw materials and the study of organoleptic and functional and technological properties of developed minced meat systems and finished products. The research has been carried out on the rational combining of meat and fish raw materials and the expansion of assortment of minced semi-finished products. The formulations of minced meat systems for the production of meat semi-finished with a partial replacement of the main raw material to fish raw materials have been developed. The organoleptic and functional and technological parameters of minced meat systems and finished products are investigated. According to the results of the organoleptic evaluation, it was found that partial replacement of meat raw material with minced fish does not worsen the sensory characteristics of minced meat products.

Vegetative disorders in anxiety disorder: A review
Vegetative disorders are characteristic of patients with anxiety disorders, which are becoming more common and negatively affect the quality of life of both the patients themselves and their environment. Almost 20% of the population suffers from anxiety disorders, and women are more prone to these diseases than men. Anxiety disorders include panic disorder, generalized anxiety disorder, and other disorders. In most cases, anxiety disorders are accompanied by vegetative symptoms, such as palpitations, sweating, trembling, changes in appetite and others. Vegetative disorders often mimic somatic and neurological disorders in patients with anxiety disorders, therefore they create problems for diagnosis. In our country, a significant part of patients with anxiety disorders are observed by neurologists with a diagnosis of somatoform dysfunction of the autonomic nervous system or autonomic dystonia. The therapy of the underlying disease, which includes lifestyle optimization, psychotherapy and medications, is of leading importance in reducing vegetative disorders
