The six species heavy ion beam was accumulated with the help of electron cooling in the main ring of Cooler Storage Ring of Heavy Ion Research Facility in Lanzhou (HIRFL-CSR). The ion beam accumulation dependence on the parameters of cooler was investigated experimentally. The 400 MeV/u 12C6+ and 200 MeV/u 129Xe54+ were stored and cooled in the experimental ring CSRe, and the cooling force was measured in different conditions.

The significant reduction of sediment load flux into Lake Baikal from its main tributary-the Selenga River began in the mid-1970 s,and can be explained by climate change and socio-economic *** analysis was done of changes in hydro-meteorological parameters(water discharge,sediment load,air temperature,and precipitation) and their tendencies over periods of 1946-1975(baseline) and1976-2017(warming).Changes in natural processes and human activity were negligible during the baseline *** the warming period,against the background of an increase in temperature,the water discharge had a slight decreasing trend(-13%) whereas the sediment load has significantly decreased(-53%) these are consist with the precipitation change(-9.4%).Analysis of hydro-climatic data using statistical methods showed that in the warming period the greatest reduction in river sediment runoff occurred in the interval *** this period the sediment load was 768 × 10～3 t/yr,which is less than the average value during the warming period-1048 × 10～3 t/*** sedimentation in the Selenga River delta,the actual sediment load flux from the Selenga River into Lake Baikal amounted to 515 × 10～3 t/yr,which is three times less than the average multiyear value 1535 × 10～3 t/yr for observation period(1946-2017).

Using the three-component spectral model describing the FIRAS average continuum spectra, the exact analytical expressions for thermodynamic and radiative functions of Galactic far-infrared radiation are obtained. The COBE FIRAS instrument data in the 0.15-2.88 THz frequency interval at the mean temperatures of T1= 17.72 K, T2= 14 K and T3= 6.73 K are used for calculating the radiative and thermodynamic functions, such as the total radiation power per unit area, total energy density, total emissivity, number density of photons, Helmholtz free energy density, entropy density, heat capacity at constant volume and pressure for the warm,intermediate-temperature and very cold components of the Galactic continuum spectra. The generalized Stefan-Boltzmann law for warm, intermediate-temperature and very cold components is constructed. The temperature dependence of each component is determined by the formula IS-B（T） = σ′ T6. This result is important when we construct the cosmological models of radiative transfer that can be applied inside the Galaxy. Within the framework of the three-component spectral model, the total number of photons in our Galaxy and the total radiation power（total luminosity） emitted from a surface of the Galaxy are calculated. Their values are N6Gtotal= 1.3780 × 108 and I3Gtotal（T） = 1.0482 × 106 W. Other radiative and thermodynamic properties of the Galactic far-infrared radiation（photon gas） of the Galaxy are calculated. The expressions for astrophysical parameters, such as the entropy density/Boltzmann constant and number density of the Galactic far-infrared photons are obtained. We assume that the obtained analytical expressions for thermodynamic and radiative functions may be useful for describing the continuum spectra of the far-infrared radiation for other galaxies.

The paper looks at the issue of the relationship between Marx and Marxism. Three approaches to the issue,which are widespread in contemporary Marxist literature and among marxologists are discussed. The first approach: the true Marx is the philosophy of Marx minus political theory. The second approach: the true Marx is the philosophy of Marx plus political theory of social-democratic parties. The third approach: the true Marx is the philosophy of Marx plus political theory,developed most fully by Lenin in the preparation of the R ussian revolution. The third approach,from our point of view,corresponds most to the essence of genuine Marxism,at least as applied to the twentieth century. The paper examines in detail the principal novelty of Lenin speaking of the need to translate Marx's materialistic theory of history to the political level as a theoretical issue. The author also notes the contribution of the Chinese leaders into further development of the political theory of Marxism closely connected with the issues of strategy and tactics of building socialism with Chinese characteristics. In conclusion,the paper states that world history nowbecomes increasingly complex and mixed. Therefore,the question of whether Marxist philosophers in this situation will be able to find ways of realization the 11th thesis of Marx "On Feuerbach"remains open.

A Usov-type quantum model based on a mean-field approximation is utilized to simulate the magnetic structure of an assumed rare-earth nanoparticle consisting of an antiferromagnetic core and a paramagnetic outer *** study the magnetic properties in the presence and absence of an external magnetic *** simulation results show that the magnetic moments in the core region orientate antiferromagnetically in zero external magnetic field;an applied magnetic field rotates all of the magnetic moments in the paramagnetic shell completely to the field direction,and turns those in the core(which tries to maintain its original antiferromagnetic structure)towards the orientation in some degree;and the paramagnetic shell does not have a strong influence on the magnetic configuration of the core.

We employ a two-ion model to calculate the spontaneous magnetization and susceptibility of TbNi2B2C with the mean-field theory, and derive an analytic formula for the Néel temperature of the material with the perturbation theory. In both the cases, only the four lowest crystal-electric-field （CEF） states are taken into account as base functions. Our theoretical results are consistent with the experimental data, manifesting the strong effects of the low lying CEF states on the magnetic behaviors of the material and the suitability of the theoretical approach proposed here.
