The paper investigated the redistribution of hydrogen and deuterium in the assemblies of metallic foils Ta | CD2 | Ta, Ta | Ta | CD2 | Ta | Ta and Nb | CD2 | Nb, irradiated pulses of high-argon plasma at a plasma focus. Irradiated samples foils were investigated by detection of recoil nuclei of hydrogen and deuterium (ERDA). It found ultradeep penetration in the target light gas impurities (hydrogen and deuterium). It is assumed that this phenomenon is due to the influence of shock waves generated by a plasma pulse, and acceleration of diffusion processes.
The work carried out research on the use of pulsed high-temperature plasma for the preparation of compounds of immiscible materials. The technique of irradiation on materials installation type Plasma Focus.
There are many different methods of deposition of films on the dielectric material and the metal surface , such as magnetron sputtering and thermal materials , methods, and electrolytic chemical deposition , etc. However , after the film deposition to improve their adhesion to the substrate is necessary to apply chemical and thermal treatment, which often leads to uncontrolled changes in the physical properties of the films . Thus, the search for alternative methods of deposition of films that do not require additional costs for thermal and galvanic chemical treatment remains valid . This paper proposes a method of applying metallic films on glass substrates using pulsed plasma obtained by installing a Plasma Focus ; describe a scheme of the experiment and the results of investigations of the obtained films.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
