A time evolution of giant lobe-dominated radio galaxies (with projected linear size D > 1 Mpc for H0=50 km sMpc and q0=0.5) is analysed on the basis of dynamical evolution of the entire FRII-type population. Two basic physical parameters, namely the jet power Q0 and central density of the galaxy nucleus ρ0 are derived for a sample of giants with synchrotron ages reliably determined, and compare...
Plasmon modes in graphene are influenced by the unusual dispersion relation of the material. For bulk plasmons this results in a n1/4 dependence of the plasma frequency on the charge density, as opposed to the n1/2 dependence in two-dimensional electron gas (2DEG); yet, bulk plasmon dispersion in graphene follows a similar q1/2 behavior as for other two-dimensional materials. In this work we co...
We investigate the Q evolution of parton distributions at small x values, recently obtained in the case of soft initial conditions. The results are in excellent agreement with deep inelastic scattering experimental data from HERA. The measurements of the deep-inelastic scattering structure function F2 in HERA [1] have permitted the access to a very interesting kinematical range for testing the ...
In this paper, a collision friction model for double-layer MoS2 film is proposed considering the microgravity induced in space environment. A modified REBO (Reactive Empirical Bond Order) potential used to describe interactions among atoms film. The process of simulated by vibrations y and z directions, dependence average force analyzed. influence single vibration direction on forces can be ign...
today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...

Different thicknesses of 99.97% Cu are deposited on glass substrate by thermal evaporation method at the rate of 2A˚/sec. Kramers-Kronig method is used for the analysis of the reflectivity constant in the range of 200nm<λ2eV, by increasing the thickness, the imaginary part of refraction index, k, increases and real part, n, decreases. At higher energies, both constants reach the asymptotic valu...
Measurements at the prototype cavity were performed at the FZJ Jülich in order to support the design work of the SC accelerator part for the European Spallation Source (ESS) [1]. A shielded test facility has been constructed providing 25kW peak RF power operating at 500MHz [2]. The test cavity has been fabricated at ACCEL Instruments and was installed into the shielded area. This 5-cell cavity ...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
We examine the likelihoods of different cosmological models and cluster evolutionary histories by comparing semi-analytical predictions of X-ray cluster number counts with observational data from the ROSAT satellite. We model cluster abundance as a function of mass and redshift using a Press–Schechter distribution, and assume that the temperature TðM; zÞ and bolometric luminosity LXðM; zÞ scale...
