    Quark Model and Neutral Strange Secondary Production by Neutrino and Antineutrino Beams

    Full text link
    The experimental data on K0K^0 and \Lambda production by \nu and \bar{\nu} beams are compared with the predictions of quark model assuming that the direct production of secondaries dominates. Disagreement of these predictions with the data allows one to suppose that there exists considerable resonance decay contribution to the multiplicities of produced secondaries.Comment: 6 pages, no figures, 2 table

    The experimental data on the interactions of light nuclei (d, He(4), C(12)) at the momentum 4.2 GeV/cA with the carbon nuclei were taken in the 2-m propane bubble chamber. The distributions in the number of interacting nucleons, the spectra of protons, the mean energies of secondary pions and protons, the mean fractions of energy transferred to the pion and nucleon components are presented. The results of the investigation of the mechanism of nucleus-nucleus interactions can be used to calculate the nuclear cascades in the atmosphere

    In Russian law, the term "good faith" ("good conscience") refers to different concepts: "honest practice" and "ignorance of the fact when such ignorance generates legal consequences." The article investigate聽 the educational aspects of distinguishing 聽objective and subjective good faith. The questions of application of the rules on subjective good faith to the relations arising in connection with the establishment, circulation and protection of civil rights are considered. The analysis of the content of the legal regime of objects of absolute property rights (things, property security, share in the right of common property, corporate rights) allowed us to conclude that the consideration of the rules on subjective good faith is a natural, necessary element of the legal regime of any object of civil turnover, and the real question is only the recognition of such an element of the legal regime by the rule of law and the definition of the features of its application.En la ley rusa, el t茅rmino "buena fe" ("buena conciencia") se refiere a diferentes conceptos: "pr谩ctica honesta" e "ignorancia del hecho cuando tal ignorancia genera consecuencias legales".

    Quantum fluctuations, quanta of electromagnetic interaction, quantum electronic bound states

    Full text link
    Based on the concepts of the quantum field theory of virtual photons as quanta of electromagnetic interaction, we discuss the physical content of the phenomena underlying the principle of quantum uncertainties. We consider the features of the uncertainty relations and the properties of the elementary particles (electrons, protons, etc.) under the conditions of the formation of quantum bound states at atomic and subatomic distances

    The theoretical DFT study of electronic structure of thin Si/SiO2 quantum nanodots and nanowires

    Full text link
    The atomic and electronic structure of a set of proposed thin (1.6 nm in diameter) silicon/silica quantum nanodots and nanowires with narrow interface, as well as parent metastable silicon structures (1.2 nm in diameter), was studied in cluster and PBC approaches using B3LYP/6-31G* and PW PP LDA approximations. The total density of states (TDOS) of the smallest quasispherical silicon quantum dot (Si85) corresponds well to the TDOS of the bulk silicon. The elongated silicon nanodots and 1D nanowires demonstrate the metallic nature of the electronic structure. The surface oxidized layer opens the bandgap in the TDOS of the Si/SiO2 species. The top of the valence band and the bottom of conductivity band of the particles are formed by the silicon core derived states. The energy width of the bandgap is determined by the length of the Si/SiO2 clusters and demonstrates inverse dependence upon the size of the nanostructures. The theoretical data describes the size confinement effect in photoluminescence spectra of the silica embedded nanocrystalline silicon with high accuracy.Comment: 22 pages, 5 figures, 1 tabl

    Laser welding of metal-polymer-metal sandwich panels

    In the production of metal-polymer multilayer composite parts, e.g., for automotive applications, the possibilities of thermal joining are limited due to the instability of the polymer core at elevated temperatures. Accordingly, such materials require a special approach to their welding. The three-layered metal-polymer-metal samples were made of DPK 30/50+ZE dual-phase steel as cover sheets that were electrolytic galvanized, and a polypropylene-polyethylene foil as core material, with thicknesses of 0.48/0.3/0.48 mm. The samples were welded on both sides using a 1.06 渭m Nd:YAG ROFIN StarWeld Manual Performance laser. Significant improvements of the welding conditions are achieved by machining the edges of materials to be welded. The parameters of laser welding were chosen in such a way that the polymer structure remained almost unchanged. The weld thickness was about 40% of the thickness of each steel layer. It was established that within the selected laser processing parameters the melting occurred uniformly, while the polymer layer practically did not change its structure. Therefore, it can be stated that two-sided joint welding of metal-polymer-metal composite sandwich panels, without significant degradation of the polymer core layer, is feasible
