We consider how to interpret, filter, and cross-correlate complex-value color (hue and saturation) images by using a single discrete Fourier transform: the spatiochromatic discrete Fourier transform. The model defines new types of spatiochromatic oriented sinusoidal gratings, termed rainbow gratings, which encode the variation of color over space. We(More)
The production by stress of gastric lesions in rats was inhibited by metiamide and by mepyramine. Lesions induced by indomethacin treatment were inhibited by mepyramine but not by metiamide. Those induced by aspirin treatment in pylorus-ligated rats were not affected by either antihistamine drug. Oral glutamine inhibited lesion production in all three(More)
A total of 523 chilled beef and lamb carcases were sampled from four abattoirs and 13 very small plants (VSPs) in South Australia during March 2002 in order to develop a microbiological profile of meat produced for domestic consumption within the State. Aerobic viable counts (AVCs) and Escherichia coli counts were obtained from samples taken by(More)
1. Most models of growth are simply mathematical descriptions of growth trajectories. They are evaluated empirically based on goodness of statistical fit. 2. Recently we (West et al . 2001) presented a theory of growth based on first principles of energy conservation and allocation. The critical parameters are defined precisely and operationally in terms of(More)
1. Rats genetically resistant to dextran and other agents producing the anaphylactoid reaction (NR rats), have a higher polymorph count than do rats which react to these agents (R rats).2. NR rats do not develop polyarthritis when a hind paw is injected intradermally with Freund's adjuvant.3. The polyarthritis produced by an intravenous injection of(More)

Intracutaneous injections of three glucan contaminants of invert sugar solutions and crude cane sugar into human skin produced localised wheals and erythema reactions. These glucans of molecular weight between 12,000 and 1,400,000 were also active on intradermal injection into both dextran-sensitive and dextran-resistant rats, and, like dextrans, were(More)
