Determination of the Element Distribution in Films Deposited using the Plasma Focus Facility by Rutherford Backscattering
C, Cu and W element profiles in films deposited using Plasma Focus facility (PF-4, FIAN) were studied by the method of Rutherford backscattering of 2 MeV He+ ions. The films were deposited on glass substrates in the Ar orifice gas. The element profiles were found to depend significantly on the particle kinetic energy. The penetration depth of particles with ~105 m/s speed was about 1.5 μm. The corresponding glass thickness element profiles were non-linear. For each element, there was the maximum layer depth under the glass surface. The formation of Cu, W and C layers under the glass surface and their overlapping was the feature of the films deposited using the PF-4 facility. Such an arrangement of layers told significantly this method of film deposition from the conventional methods used low deposition atom rates, as well the diffusion. Because of mentioned characteristics of deposition, the obtained films were dielectrics.
This chapter focuses on the analysis of post-Soviet films and TV series dedicated to the medical profession, and it explores how the perception of gender and the representation of work practices among this professional group have changed in recent decades. The new cinematographic images are considered to be a result of Western cultural impact (after 1991) and Soviet cultural legacies. The 2000s witnessed the return of the special attention to “doctors” and “medical professionals” as the heroes of post-socialist drama and melodrama. However, these images are often misogynistic, and it is possible to say that cinematographic metaphors reflect developments in social attitudes.
The method of Rutherford back scattering of He + ions with 2 MeV studied the distribution profiles of the elements C, Cu and W in the films deposited on the discharge installation type "plasma focus". The films are deposited on glass substrates in Ar plasma-forming gas. It is found that the element distribution profiles vary significantly from the kinetic energy of the particles. Particles having a velocity about 105 m / s, penetrates to a depth of about 1.5 microns. Appropriate distribution profiles elements for glass thickness are nonlinear. For each element, there is a maximum depth of the layer under the surface of the glass. A feature of the films obtained on the setting of "plasma-focus" is the formation of layers of the elements Cu, W and C at the glass surface and their mutual overlap. This arrangement of layers distinguishes described film deposition method of the commonly used methods of application at low speeds the deposition of atoms, as well as by diffusion. It is found that the obtained film are insulators.
In the paper it has been researched diffusion of phosphorus in thermal SiO2 films on MIS structure and influence of the process on charge effects in gate dielectric and at interfaces at Fowler-Nordheim high-field tunnel injection of electrons.
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.

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.
