The effect ionizing radiation and hypomagnetic conditions have on the lettuce seeds of Lactuca sativa L is studied on the 120-cm cyclotron at Moscow State University's Skobeltsyn Institute of Nuclear Physics. The seeds are irradiated with deuterons having an energy of ~13.7 MeV at doses of 65 Gy, 0.55, and 5.5 kGy. They are then germinated under conditions of a geomagnetic field weakened by 50 and 10 3 times. The change in the response of seeds to radiation exposure depending on the attenuation of the geomagnetic field is analyzed.

The biological effects due to hypomagnetic field (HMF) is a very important subject for aerospace travelling and space station living, and a large number of studies on the bioeffects of the HMF have been carried out; however, many essential problems, such as physical mechanism, the harmful for human beings and other living organism of the biological effects, are still remaining unknown. In order to promote the solution to these problems, we assembled, classified and analyzed the studies on the biological effects due to the HMF. About one of the essential problem, i.e. the physical mechanism of the biological effects of HMF, we think that the yield  of the singlet spin state of the radical pair theory, that is) sin sin 4

Abstract. Methods for making nanocrystalline alloys have been discussed. Temperature dependences of the surface tension (σ), electric resistivity (ρ), magnetic susceptibility (χ) and kinematic viscosity (ν) have been obtained. Comparison of the properties of amorphous ribbons obtained by the pilot and serial technologies has been conducted. Science-based technology of multi-component alloy smelting makes it possible to prepare equilibrium smelt, the structure of which has a significant effect on the properties of the amorphous ribbon before spinning and kinetics of its crystallization has been offered.Introduction. Soft magnetic iron-nickel, iron-cobalt, iron-chromium and other high alloys have special physical and physicochemical characteristics. They are determined not only by an exact chemical composition, but also by factors of their production. Normal magnetic properties corresponding to the normative and technical documentation can be achieved by smelting in open furnaces. To obtain alloys with better and high magnetic properties vacuum units and smelting processes are used [1][2][3][4].Distinctive features of soft magnetic alloys are their high magnetic permeability, low coercive force, ability to be treated by plastic deformation, and higher specific electrical resistivity.Such indicators are achieved by adding nickel, cobalt, chromium, manganese, molybdenum, silicon and other elements to the alloys composition. Along with smelting processes hard metal heat treatment is very important [5]. However, structural features of steels and alloys which above all are determined by the selectivity of hardening phases and accompanied by the segregation of elements have a considerable influence on the properties of metal products. Main part. The production of nanocrystalline materials with particle size from 1 to 10 nm and soft magnetic amorphous alloys improved special characteristics of products considerably.The easiest method to obtain nanocrystalline powders is to evaporate material at a controlled temperature either under inert gas with subsequent condensation of steam or in the reaction zone with the formation of spherical particles, or on surfaces, where particles have faceting.A plasma-chemical method of obtaining nanopowders is the most common chemical methods among others. The reaction is carried out in non-equilibrium conditions providing for a high rate of nucleus formation of the new phase and a low speed of their growth.A nanoparticle deposition in colloidal solutions involves the consistent implementation of the following operations: a synthesis of starting reagents of the solution and a reaction termination at a particular point in time, after which the disperse system changes from a liquid colloidal state into a dispersed solid one. The method has high selectivity and allows producing particles with a very narrow size distribution.
