LORENTZ QUANTUM ELECTRODYNAMICS
01.00.00 Physical-mathematical sciences
Description
The question of extending the Lorentz electrodynamics to quantum theory is discussed. The system of equations of the Lorentz quantum electrodynamics was established

NEUTRON STRUCTURE IN KALUZA-KLEIN THEORY
01.00.00 Physical-mathematical sciences
Description
The special states of a hydrogen atom, arising from the interaction of a proton with a scalar massless field studied on the basis of Kaluza-Klein theory. It is shown that some states of the atoms have parameters of the neutron.

01.00.00 Physical-mathematical sciences
Description
Article is devoted to the numerical analysis of regional problems for system of the equations of Nernst-Plank-Puasson (NPP), to application of these regional problems to modeling and studying of mass transfer in the channel desalting of electro dialysis device. Various mathematical models of the transfer of ions in potential static mode in the form of system of the quasilinear equations with private derivatives are offered. The basic rules of occurrence and development of a spatial charge in the channel desalting of electro dialysis device are revealed

DEVELOPMENT OF MATHEMATICAL MODEL OF PROCESS OF HEATING OF AIR FOR DRYING GRAIN
01.00.00 Physical-mathematical sciences
Description
In the article, the analytical way of working out of mathematical model of process of heating of air for grain drying is shown. It is considered, that the temperature of a wall influences on dynamics of process of heating. Dynamic characteristics of the top internal device are considered. With use of package Mathcad schedules of transitive functions on operating and revolting influence are received. Results of modeling are presented

ELECTRICAL PROPERTIES OF A THIN LAYER OF A MAGNETIC FLUID WITH A GRAPHITE FILLER IN A MAGNETIC FIELD
01.00.00 Physical-mathematical sciences
Description
The electrical properties of the thin magnetic fluid layer containing the dispersion of graphite microparticles are studied. The influence of the external magnetic field on the peculiarities of the electrical properties is investigated

Description
Dendroclimatic analysis of stands of radial increment of the natural forest and forest plantations of Scots pine in the Khrenovoe pine forest, growing in dry-moist site conditions is conducted. Cyclic dynamics of increment, weak expression of the low-frequency oscillation amplitude in the plantations stands is revealed. Direct correlation with precipitation has increased over the past 40 years, in complex suboron – to 0,48 – 0,50

BIOLOGICAL RECULTIVATION OF OVERBURDEN ROCKS IN KURSK MAGNATIC ANOMALY (KMA) REGION
Description
The results of biological recultivation of disturbed lands are offered in the article. Silvicultural and taxation parameters of basic wood types of dumps and their role in stable ecosystem formation are presented

LARGEFRUITNESS OF WILD ROSE ON THE SLOPE OF THE FOOTHILLS OF KABARDINO-BALKARIA
Description
Products, received from hips (fruits of wild roses), are profit a high consumer demand, that dictate solutions, which connected with technology of improvement natural dense bushes and creating artificial planting the most valuable in economic relation forms. In connection with it different characters of allocation of wild rose’s bushes is revealed by indicator of size of hips

RADIOECOLOGICAL RISKS OF BOVINE LEUCOSIS SPREAD IN CHELYABINSK REGION
Description
Radioecological risks of bovine leucosis spread among cattle in Chelyabinsk region are estimated. The obtained data can be used for simulation modeling and the forecasting of leucosis prevalence in the conditions of ecological troubles
