We present the hetero-epitaxy of III-V materials on 200 mm Silicon wafers by MOCVD. A Ge layer is first grown on the silicon wafer by a two-step process, allowing a lattice matched GaAs layer to be grown on top. Anti-phase boundaries formation are avoided by using a high growth temperature and an arsine partial pressure above 5 mbar during the nucleation of the GaAs layer. The resulting GaAs vi...

This report of a phase 2 trial of thalidomide (THAL) (200 mg/d; 200 mg increment every 2 weeks to 800 mg) for 169 patients with advanced myeloma (MM) (abnormal cytogenetics (CG), 67%; prior autotransplant, 76%) extends earlier results in 84 patients. A 25% myeloma protein reduction was obtained in 37% of patients (50% reduction in 30% of patients; near-complete or complete remission in 14%) and...

The first use of concrete block paving for improving existing aircraft pavements was made at London Luton Airport UK in October 1981. Initial trials comprised two rectangular panels each 9 m x 2 m constructed on an apron stand directly beneath undercarriage gear positions. Rectangular block paving units 100 mm x 200 mm x 80 mm thick were used as an inlay to replace damaged bituminous overlay ma...

Few thorough comparisons of the systemic effects of inhaled corticosteroids in children are available. The aim of this study was to compare the effect of budesonide and fluticasone propionate on short-term lower leg growth. Fluticasone propionate, budesonide and placebo were administered for 2 weeks in a randomized, double-blind, double-dummy, cross-over design. Twenty four children aged 6-12 y...

OBJECTIVES Although haematological abnormalities are common manifestations of HIV infection, few studies on haematological parameters in HIV-infected persons have been undertaken in sub-Saharan Africa. The authors assessed factors associated with haematological parameters in HIV-infected antiretroviral-naïve and HIV-uninfected Rwandan women. STUDY DESIGN Cross-sectional analysis of a longitud...

To evaluate potential alternatives to conventional fungicides to control decay, more than 20 food additives and generally regarded as safe compounds were tested at three concentrations in in vivo primary screenings with several cultivars of California peaches, nectarines, and plums that had been artificially inoculated with seven major postharvest pathogens: Monilinia fructicola, Botrytis ciner...

Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...

This paper outlines recent developments in two dominant classes of Silicon Carbide based switches – the Super Junction Transistor (SJT) for 1.2kV-6.5kV pulse width modulated switching; and Thyristors for >6.5kV cycloconverter and pulsed power operation. The high-temperature (> 200 °C) blocking voltage, on-state and switching performance of recently fabricated 1200 V-class, 4H-SiC Super Junction...
