This study investigated the perceptual adjustments that occur when listeners recognize highly compressed speech. In Experiment 1, adjustment was examined as a function of the amount of exposure to compressed speech by use of 2 different speakers and compression rates. The results demonstrated that adjustment takes place over a number of sentences, depending(More)
The submarine hydrothermal activity on and near the Galápagos Rift has been explored with the aid of the deep submersible Alvin. Analyses of water samples from hydrothermal vents reveal that hydrothermal activity provides significant or dominant sources and sinks for several components of seawater; studies of conductive and convective heat transfer suggest(More)
Faecal material of leopard, crabeater and elephant seals was collected from the vicinity of Davis station, Antarctica. Very few identifiable remains were found in elephant seal droppings. Fish remains, mainly of Pleuragramma antarcticum, were found in both leopard and crabeater seal droppings. The mysid Antarctomysis maxima was also found in crabeater seal(More)
Weddell seal vocalizations were recorded once a fortnight throughout 1984 at a major pupping site near Davis, Antarctica. Few vocalizations were heard between January and June. The number of vocalizations recorded increased from July to a peak in November and early December during the breeding period and then fell off rapidly through December. The increase(More)
An experimental search for an electric dipole moment (EDM) of the neutron has been carried out at the Institut Laue-Langevin, Grenoble. Spurious signals from magnetic-field fluctuations were reduced to insignificance by the use of a cohabiting atomic-mercury magnetometer. Systematic uncertainties, including geometric-phase-induced false EDMs, have been(More)
Within Prydz Bay (Antarctica) Euphausia crystallorophias was found to be restricted to the continental shelf (<1000 m). Densities greater than 1000 indiv. 1000 m-3 were observed nearer the coast, while lower densities were seen further offshore. E. crystallorophias was the dominant euphausiid in the shelf region with the occurrence of Euphausia superba(More)
The food of emperor penguins Aptenodytes forsteri at the edge of the sea ice off the Vestfold Hills was studied by faecal analysis. Fish, crustacean, cephalopod and gastropod remains were found in 151 droppings collected between August and October 1984. The main fish identified from otoliths was Pleurogramma antarcticum with an average standard length of(More)
A 0.9 to 1.5 kW, 2.45 GHz atmospheric pressure air microwave plasma torch has been operated efficiently with less than 1 % reflected power. The plasma is sustained in a 28 mm internal diameter fused quartz tube which penetrates perpendicularly through the wide walls of a tapered and shorted WR-284 (72 x 17 mm cross-section) waveguide. A study has been made(More)
A simplified stochastic model for the fiber structure of paper is introduced. The packing density and optical thickness of the fiber network are derived analytically, and their dependence on fiber characteristics can be seen. We undertake a Monte Carlo simulation of light scattering that is based on geometrical optics, using a realization of the model,(More)
. The number of predators from Heard Island foraging in shelf waters, their prey requirements, and the proportion of their diet that was commercial and non-commercial fish were estimated. The calculated annual consumption of commercial fish species varied between 36,360 and 84,166 tonnes. The non-commercial Krefftichthys anderssoni was the preferred prey(More)
