In this study, expressions for the radiation quality factor Q and the input impedance seen at any terminal of a multiport antenna are derived. It is shown computationally that because of the possibility to adjust the antenna current distribution through suitable feeding/loading a multiport antenna can perform lower Qs than a similar single-port antenna. © 2008 Wiley Periodicals, Inc.

cose is replaced by a carbon atom, have been extensively studied during the last three decades. It has been shown that the conformation of C-glucosides is significantly different from that of O-glucosides. C-Glucosides are stable to enzymatic as well as acidic degradation, which is why they have potential as hydrolytically stable O-glucoside analogs for enzyme inhibitors. The microflora in the ...

This paper investigates whether there is a correlation between a poor Visual Attention Span (VAS) and the child’s optometric status. Convergence excess impacts most upon a male achieving a VAS-3 more than 75 per cent of the time. Fifty per cent of females with eye-teaming problems are unlikely to achieve a VAS-3 more than 25 per cent of the time. Overall children with an optometric diagnosis we...

Standard fermentations were performed as follows: A spore suspension was inoculated into 3 L of the following medium: sucrose, 3 per cent; corn steep liquor, 1 per cent; molasses, 0.1 per cent; NaCl, 0.05 per cent; and CaCO3, 0.4 per cent. The fermentations were carried out at 27 C in 5-L fermentors (Bartholomew, Karow and Sfat, 1950). After 36 hours, 100 ml of the culture fluid was transferred...

1. By means of the Warburg-Barcroft microrespirometer apparatus and the Warburg direct method, the relative effect of caffeine upon the O(2) consumption of the fertilized egg of Arbacia punctulata was shown for the following concentrations in sea water: 0.002 per cent (M/10,000), 0.004 per cent (M/5,000), 0.02 per cent (M/1,000), 0.1 per cent (M/200), 0.2 per cent (M/100), 0.5 per cent (M/40), ...
