• A prospective, randomized, double-blind study was carried out to determine whether vitamin C prophylaxis, 2.0 g/day, vs placebo prophylaxis would reduce the incidence or morbidity of the common cold and other respiratory illnesses in 674 marine recruits during an eight-week period. Whole-blood ascorbic acid levels measured six weeks after initiation of the study were significantly higher in the vitamin C group. There was no difference between the two groups in the incidence or duration of colds. The vitamin C group rated their colds as being less severe, but this was not reflected in different symptom complexes or in fewer sick-call visits or training days lost. This study and the literature do not support the prophylactic use of vitamin C to prevent the common cold

A 20 watt micro-strip x-band AlGaN/GaN HPA MMIC for advanced radar applications
In this paper a first iteration design, fabrication and test of a two-stage X-band MMIC HPA in micro-strip AlGaN/GaN technology is reported. With 20 V drain voltage operating bias point, at 3 dB compression point, the HPA delivers a pulsed output power ranging from 21 to 28.5 W, an associated gain from 12.9 to 16.5 dB and an associated PAE from circa 30% to 40%, over the 8-10.5 GHz frequency bandwidth. In the best performance frequency points (8.5 and 9 GHz) the HPA exhibits a saturated output power of 30 W with an associated PAE of 40%
