[en] A review of the theories and some selected experimental data is made in connection with the causes of variation in electrical resistance of thin metallic films during gas adsorption. (author)

[en] Starting from the experimental fact that the angular distribution of black evaporation prongs in the p-nucleus interactions is symmetrical, the number of recoil nucleons may be related with the number of collisions ν. Since a rigorous separation of the black evaporation prongs (Nsub(b)) is difficult to achieve, the angular distribution of black and grey prongs (Nsub(h)) was measured in about 7000 interactions of protons of 10 GeV with emulsion nuclei, being established a relation of dependence between the mean number of collisions ν and the anisotropy of angular distribution of slow particles at fixed Nsub(h).

[en] Methodic problems of measurement of beta-spectra by means of ST-2 iron-free beta-spectrometer with toroidal magnetic field were studied. Construction characteristic features and their effect on beta-spectra distorsion were considered. Detector efficiency at registrating beta-particles, of background distribution at measurement of beta-spectra distribution factor as well as factors due to source production quality were investigated. It is established that the response function for the magnetic beta-spectrometer ST-2 can be described by the function ''Gauss + exponential-tail''. The programme ''BETARZ'' is discussed used for processing the beta-spectra both for allowed and forbidden transitions. The results obtained allow to perform corresponding corrections at processing. The investigation has been performed at the Laboratory of Nuclear Problems, JINR. (author)

[en] The theoretical interpretations of the equilibrium properties of crystallising systems are presented. Because the growth of crystals from solutions is a very complex process, which is completed in several stages, it is not possible to expect theoretical relations to yield a quantitative agreement with data obtained in practice.

[en] A survey of the estimations of the unknown nuclear masses by means of the generalized mass relations is presented. One discusses the new hypotheses supplementing the original general Garvey-Kelson scheme, reviewing the generalized mass relations and formulae, according to the present status of this new formalism. A critical discussions is given of the reliability of these new Garvey-Kelson type extrapolation procedures. (author)

[en] In view of theoretical estimates of neutron cross-sections, presented in part I, the most important models associated to reaction mechanisms are discussed. (author)

[en] ''In situ'' investigations of the natural and forced infiltration and retention of the fissionable elements from a liquid residue in several natural compacted soils and compacted clays are presented. The velocities and flow rates for different stages of the residue infiltration are determined. The retention of the fissionable elements by variation of the fissionable element concentration with the distance from the place of the residue depot is investigated. (author)

[en] An outline of the theoretical treatment of the one-particle transfer reactions and of the spectroscopic information extracted from the study of these reactions is given. (author)

[en] A compilation of the data appeared in literature on the working principle, efficiency and performances of a solid electrolyte Fuel Cell, based on stabilized zirconia is presented. The pressure dependence of the ZrO₂ electrolytic domain limits is also discussed. (author)
