Impurity induced disordering of GaInAs quantum wells with barriers of AlGaInAs or of GaInAsP

Impurity induced disordering of GaInAs quantum well structures with barriers of AlGaInAs and of GaInAsP has been investigated using boron and fluorine. The impurities were introduced by ion implantation followed by thermal annealing. Annealing unimplanted P-based quaternary material at temperatures greater than 500° C caused a blue shift of the exciton peak. At annealing temperatures greater than 650° C red shifts in the exciton peak of unimplanted Al-based quaternary material were observed. Boron implantation caused small blue shifts of the exciton peak in both material systems at low annealing temperatures. Much larger blue shifts were observed in the fluorine implanted samples.     

An analytical expression for the power coefficient of an ideal horizontal-axis wind turbine

The paper shows that an analytical evaluation of the power coefficient C_p for an ideal horizontal-axis wind turbine can be made via an expression giving the direct relationship of C_p and the axial induction factor a. The results obtained agree closely with those obtained numerically from the usual integral expression involving several variables.     

Use of oxygen for the cleaning, passivation, and preservation of power-generating equipment at the Kharanorskaya SAPP

Studies conducted on two power-generating units at the Kharanorskaya SAPP relative to the steam-water-oxygen passivation, preservation, and partial cleaning of all boiler-heating surfaces, including the surfaces of the reheater, and passivation of the surfaces of the high-pressure heaters on the steam and water sides by the steam-oxygen method, as well as partial passivation, preservation, and cleaning of turbine blading are presented. __________ Translated from élektricheskie Stantsii, No. 6, pp. 56–64, May, 2006.     

Technical risk involved in long-term operation of steam turbines

The scope of the paper is the assessment of the technical risk involved in long-term operation of power units. Detailed analyses have been conducted for steam turbine components. The sources and consequences of risk have been identified and the probability of turbine components failure calculated. The quantitative assessment of the risk has been made and possibilities of its reduction discussed.
