introduction according to the definition of world meteorology organization (wmo), as the speed of the air mass is more than 30 meters per second, the jetstream will arise. the core of the jetstream is with baroclinic atmosphere due to the large difference in temperature and wind speed. there are two west jetstreams in the northern hemisphere. the northern jet stream is called polar front jetstr...

The shapes of jets with transverse energies, E jet T , up to 45 GeV produced in neutral-current(NC) and charged-current (CC) deep inelastic e + p scattering (DIS) at Q 2 > 100 GeV 2 have been measured with the ZEUS detector at HERA. Jets are identiied using a cone algorithm in the ? ' plane with a cone radius of one unit. The jets become narrower as E jet T increases. The jet shapes in NC and C...

This article gives the perturbative NNLO results for the most commonly used event shape variables associated to three-jet events in electron-positron annihilation: Thrust, heavy jet mass, wide jet broadening, total jet broadening, C parameter and the Durham three-to-two jet transition variable. In addition the NNLO results for the jet rates corresponding to the Durham, Geneva, Jade-E0 and Cambr...

Our recent VLBI observations of the prominent FR II radio galaxy Cygnus A with the EVN and the VLBA reveal a pronounced two-sided jet structure. from which we could derive the kinematics of the jet and counter-jet. On the jet side and on mas scales, the jet seems to accelerate from βapp ≈ 0.1 − 0.2 (Krichbaum et al. 1998) at core-separations near 1 mas to βapp ≈ 0.4 − 0.6 at r ≥ 4 mas (H0 = 100...

since treatment of landfill leachate is quite complicated, there is a need to develop a system thatis capable of providing high treatment efficiencies. in this study, the treatment performance of a jet - loopmembrane bioreactor (jlmb) operated at different organic loading rates was investigated by observing thechanges in chemical oxygen demand (cod), total kjehldahl nitrogen (tkn) and total amm...

noise exposure is one of the main problems in petroleum industry. petroleum in dustry is a strategic industry in iran with large number of workers whom are exposed to different noise sources. identification and evaluation of this noise sources and reducing excessive noises are big issues in petroleum industry from point of occupational health. this descriptive-analytic study was performed in th...

vanillin is an interesting corrosion inhibitor because of its safe use and high solubility inwater. the effect of vanillin on the corrosion inhibition of carbon steel in 1.0 mhydrochloric acid solution has been studied using potentiodynamic polarization,electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques.the effect of temperature on the rate of corrosion in th...

In this research, a bench-scale installation was tested for the heterogeneous electro-Fenton treatment of clofibric acid. The setup consists pressurized flow-through electrochemical cell equipped with catalyst fluidized-bed and aerated jet mixer. novelty research is two-fold: use pressurized-jet aerator on an it one first studies combining pressure catalysis in electro-Fenton. Moderate relative...
