Practice of Application in Cases of Terrorist Crimes, Problems of Law Enforcement
This article provides an analysis of the rules on criminal responsibility for terrorism and hostage-taking and certain signs of corpus delicti The problem of qualification of terrorist crimes is relevant today One of the problems faced by the law enforcer who qualifies a terrorist act and hostagetaking is the correct determination of the signs of the composition of these related crimes In this article the authors analyze the norms of Art 205 of the Criminal Code and Art 206 of the Criminal Code the basic aspects of the differentiation of norms are disclosed the practice of law enforcement on the indicated compositions is studie
Application of Computer Simulation to Study the Features of the Austenite Isothermal Transformation in Steels
An algorithm was developed for the simulation of a phase transition in solid state which makes it possible to obtain the kinetic curves of transformation under different initial conditions (the number and arrangement of new phase nuclei, the distance between the nearest nuclei). The simulation results were analyzed using the KolmogorovJohnson-Mehl-Avrami equation and the corresponding coefficients were determined. The correlation between the simulation results and the experimental kinetics of the austenite isothermal transformation in alloyed steels was shown.

THERMAL ANALYSIS ΠΠ AVIATION GAS-TURBINE ENGINE WITH THE CIRCULATION-FREE OIL SYSTEM
The article deals with the experimental-theoretical calculation method of the thermal mode of gas-turbine engine ball bearings with the circulation-free oil system. The method is based on the experimental data processing by the law of similarity. The criterion equation to assess the power losses for driving the hybrid ball bearings, and accordingly the working temperature of the bearing, or the required air blow through the bearing support has been obtained
Electric field gradients in MgB synthesized at high pressure: Cd TDPAC study and ab initio calculation
We report the high-pressure synthesis of novel superconductor MgB and
some related compounds. The superconducting transition temperature of our
samples of MgB is equal to 36.6 K. The MgB lattice parameters
determined via X-ray diffraction are in excellent agreement with results of our
ab initio calculations. The time-differential perturbed angular correlation
(TDPAC) experiments demonstrate a small increase in quadrupole frequency of
Cd probe with decreasing temperature from 293 to 4.2 K. The electric
field gradient (EFG) at the B site calculated from first principles is in fair
agreement with EFG obtained from B NMR spectra of MgB reported in the
literature. It is also very close to EFG found in our Cd TDPAC
measurements, which suggests that the Cd probe substitutes for boron in
the MgB lattice.Comment: 10 pages, 3 figure
Probing CP Violation with the Deuteron Electric Dipole Moment
We present an analysis of the electric dipole moment (EDM) of the deuteron as
induced by CP-violating operators of dimension 4, 5 and 6 including theta QCD,
the EDMs and color EDMs of quarks, four-quark interactions and the Weinberg
operator. We demonstrate that the precision goal of the EDM Collaboration's
proposal to search for the deuteron EDM, (1-3)\times 10^{-27} e cm, will
provide an improvement in sensitivity to these sources of one-two orders of
magnitude relative to the existing bounds. We consider in detail the level to
which CP-odd phases can be probed within the MSSM.Comment: 5 pages, 4 figures; precision estimates clarified, to appear in Phys.

Background: Tissue-engineered trachea transplantation remains the last chance for a variety of patients suffering from severe cicatricial tracheal stenosis. Despite the series of carried studies, the final solution hasnβt been found. Creating a functionally complete hyaline cartilage graft in vitro still presents a fundamental problem, and a number of researchers consider it as the key to a successful tracheal tissue-engineering.Aims: The study aimed to investigate the capability of detergent complex and DNAse I for human tracheal cartilage decellularization in short-time exposition for acellular scaffold obtaining.Materials and methods: Isolated from cadaveric trachea human native cartilage was used for decellularization by ensimatic-detergent complex including Triton X-100, DMSO, and DNAse I. The scaffold was characterised by histological examinations, analysis of the residual DNA content, and cell metabolic activity colorimetric test with culture in the scaffold fragments.Results: The obtained scaffolds presented highly porous structure mostly composed of collagen and glycosaminoglycans with an insignificant residual DNA level, absence of citotoxicity, and capability for cell proliferative activity stimulation.Conclusions: Thus, the study provides a new short-time technology for hyaline cartilage decellularization in order to achieve acellular scaffolds in step with the tissue engineering requirements.ΠΠ±ΠΎΡΠ½ΠΎΠ²Π°Π½ΠΈΠ΅.

Marginal Pinning of Quenched Random Polymers
An elastic string embedded in 3D space and subject to a short-range
correlated random potential exhibits marginal pinning at high temperatures,
with the pinning length becoming exponentially sensitive to
temperature. Using a functional renormalization group (FRG) approach we find
, with the
depinning temperature. A slow decay of disorder correlations as it appears in
the problem of flux line pinning in superconductors modifies this result, .Comment: 4 pages, RevTeX, 1 figure inserte
