The feeding behavior of the nemertean Procephalothrix simulus and the effects of extrinsic factors on the feeding rates of this nemertean were experimentally studied. Procephalothrix simulus showed a typical macrophagous feeding strategy and consumed various food items. When capturing freshwater Tubifex sp., the nemerteans successfully ingested prey in

Food, feeding rates and assimilation in woodland snails
Oecologia, 1970Analyses of the faeces of seven species of woodland, litterdwelling snails (Marpessa laminata, Clausilia bidentata, Oxychilus cellarius, O. alliarius, Discus rotundatus, Arianta arbustorum and Hygromia striolata), showed that all feed predominently on higher plant material, be it living or dead. H. striolata and A.

Effect of Feeding Rate on Plastic Extrudates
International Journal of Polymeric Materials, 1998Abstract Selected grades of low density polyethylene (LDPE) polystyrene (PS) were extruded in a laboratory extruder by varying the feeding rate at different revolutions per minute and temperatures. The mechanical properties of the extruded plastic sheets were determined.

Effect of Feeding Griseofulvin on Rate of Growth of Chicks
Nature, 1961GRISEOFULVIN, originally isolated from Penicillium griseofulvum by Oxford1 et al. in 1939, is produced commercially by the fermentation of three Penicillium species: griseofulvum Dierck X, janczewskii and patalum. Brian2 et al. first described its antifungal properties in 1946, but another twelve years elapsed before Gentles3 demonstrated its efficacy ...

A Negative Feed-back Dosage-rate Meter
The British Journal of Radiology, 1948A direct reading X-ray dosage-rate meter is described, which consists of a radiation transparent thimble ionization chamber (volume ½ c.c.), connected by a thin flexible cable to a negative feed-back D.C. amplifier. The instrument is robust and cheap to manufacture. An accuracy of better than ± 5 per cent. or 1 r/min. is achieved on all ranges, and the

Crested and Feral Pigeons Feeding on Fig-Seeds: Commensalism, Feeding-Rates and Vigilance
Emu - Austral Ornithology, 1985Crested Pigeons Ocyphaps lophotes and Feral Pigeons Columba livia were observed feeding on fig-seeds which had passed through the digestive tract of Figbirds Sphecotheres viridis and so had become available to ground feeders. Although Figbirds and fig-fruits were present throughout the year, most pigeons fed on fig-seeds from March to May.
