Electrodeposition and characterization of novel ceria-doped Zn-Co composite coatings was the main goal this research. Electrodeposited were compared to pure obtained under same conditions. The effect two ceria sources, powder home-made sol, on morphology corrosion resistance determined. During electrodeposition process plating solution successfully agitated in an ultrasound bath. source particl...

Demands for higher outputs have been met by careful tailoring of steam turbines for both mechanical and electrical power generation to meet the needs of thermal efficiency and reliability at an econoinic cost. Major system components and the methods chosen for speed control are described. Important operational requirements are featured.

We analyze a model of a nonlinear bath consisting of a single two-level system coupled to a linear bath (a classical noise force in the limit considered here). This allows us to study the effects of a nonlinear, non-Markoffian bath in a particularly simple situation. We analyze the effects of this bath onto the dynamics of a spin by calculating the decay of the equilibrium correlator of the z-c...
