Meat stored at 1 to 2 C under low oxygen tensions, either in gas-impermeable packs or in controlled atmospheres, occasionally exhibited an undesirable green exudate. The green pigment was identified spectrophotometrically as sulfmyoglobin. The conversion of myoglobin to sulfmyoglobin resulted from the production of H2S by bacteria tentatively identified as Pseudomonas mephitica. This organism p...

REASONS FOR PERFORMING STUDY Equine motor neuron disease (EMND) was diagnosed in 3 horses maintained on lush, grass-based pasture. This contrasted with North American studies which identified limited or no access to green herbage as an important risk factor for EMND. HYPOTHESIS Grazing horses that have an apparently adequate intake of pasture herbage to meet normal equine vitamin E requiremen...

Lifetime of the excited state (tau) of bacteriochlorophyll (BChl) in photosynthetic bacteria, measured with a mode-locked argon laser (oscillating at 488 nm; mode locked at 56 MHz) as light source, ranged from 0.3 to 2.5 nsec. These tau values are reported with a precision of +/-0.1 nsec. The value of tau at high exciting light intensity (I) was two to three times that at low intensity. For you...

Humanity has entered a new phase of sustainability challenges, the Anthropocene, in which human development has reached a scale where it affects vital planetary processes. Under the pressure from a quadruple squeeze-from population and development pressures, the anthropogenic climate crisis, the anthropogenic ecosystem crisis, and the risk of deleterious tipping points in the Earth system-the d...

A general method for the derivation of asymptotic nonlinear shallow water and deep water models is presented. Starting from a general dimensionless version of the water-wave equations, we reduce the problem to a system of two equations on the surface elevation and the velocity potential at the free surface. These equations involve a Dirichlet-Neumann operator and we show that all the asymptotic...

How well an organism completes an ecologically relevant task - its performance - is often considered a key factor in determining individual fitness. Historically, ecomorphological studies have examined how morphological traits determine individual performance in a static manner, assuming that differential fitness in a population is due indirectly to differences in morphological traits that dete...

This paper introduces a new scheme called Green MPLS Fast ReRoute (GMFRR) for enabling energy aware traffic engineering. The scheme intelligently exploits backup label switched paths, originally used for failure protection, in order to achieve energy saving during the normal failure-free operation period. GMFRR works in an online and distributed fashion where each router periodically monitors i...

When the Higher Education Funding Council for England (HEFCE) announced its open access policy last March the news was greeted with great enthusiasm by OA advocates, who view it as a “game changer” that will ensure all UK research becomes freely available on the Internet. They were especially happy that HEFCE has opted for a green OA policy, believing that this will provide an essential green c...

The evolution over the past century of two tobamoviruses infecting populations of the immigrant plant Nicotiana glauca in New South Wales (NSW), Australia, has been studied. This plant species probably entered Australia in the 1870s. Isolates of the viruses were obtained from N. glauca specimens deposited in the NSW Herbarium between 1899 and 1972, and others were obtained from living plants in...

Introduction IT is well known to practising ophthalmologists that ephedrine is less effective as a mydriatic in subjects with deeply coloured irides than in those with light irides. This observation was first reported by Howard and Lee (1927), who stated that there was a distinct difference between Caucasians with light coloured irides and Chinese with dark irides, the former responding to smal...
