Coulomb Gaps in One-Dimensional Spin-Polarized Electron Systems
We investigate the density of states (DOS) near the Fermi energy of
one-dimensional spin-polarized electron systems in the quantum regime where the
localization length is comparable to or larger than the inter-particle
distance. The Wigner lattice gap of such a system, in the presence of weak
disorder, can occur precisely at the Fermi energy, coinciding with the Coulomb
gap in position. The interplay between the two is investigated by treating the
long-range Coulomb interaction and the random disorder potential in a
self-consistent Hartree-Fock approximation. The DOS near the Fermi energy is
found to be well described by a power law whose exponent decreases with
increasing disorder strength.Comment: 4 pages, revtex, 4 figures, to be published in Phys. Rev. B as a

Investigation of the Process of Methane-Oxygen Combustion in Steam Under the Atmospheric Pressure
In the article presented results of combustion methane-oxygen mixtures in the slightly superheated water steam under the atmospheric pressure. It is shown that exist dependence of flow rate combustible mixture and steam ratio (Gg.s./Gs) on the composition of the reacting mixture at the outlet of combustion chamber. There is a trend of increasing CO2 concentration in the reacting mixture at the outlet of combustion chamber with increase of Gg.s./Gs
Combustion of Methane-Oxygen Mixture in Steam Atmosphere
Combustion of CH4:O2 mixture in the medium of low-potential steam was studied experimentally. Results of composition combustion products are presented. It is shown that they depend on the ratio of flow rates of gas mixture and steam

MEDICAL NUTRITION FOR NON SPECIFIC ULCERATIVE COLITIS AND CROHN'S DISEASE IN CHILDREN
Disturbances of nutritive status are typical of patients with non specific ulcerative colitis и crohn's disease with such symptoms as body weight deficiency, disturbance of metabolism associated with the lack of proteins, macro and microelements, energy substrata. Nutrition plays a key role not only in the growth and development processes but also is one of the crucial factors determining the adequacy of the inflammatory response, adaptation compensatory processes. The article considers issues of medicated nutrition under this pathology, including the basic diet, usage of specialized mixes and enteral feeding to correct the protein energy disturbances, and as an independent treatment method.Key words: crohn's disease, non-specific ulcerative colitis, children, diet, enteral feeding, bowel disease
