Filtering and feeding rates of cyclopoid copepods feeding on phytoplankton

Hydrobiologia, 1991
The algal biomass ingested by omnivorous cyclopoid copepods (Cyclops kolensis and C. vicinus) was measured by two methods in the hypertrophic Heiligensee in Berlin (West Germany). The clearance and ingestion rates inferred from measurements of natural populations of 14C labelled phytoplankton were compared with those obtained from chlorophyll a ...

Achievable Rates for Multiple Descriptions With Feed-Forward

IEEE Transactions on Information Theory, 2011
The two-channel multiple descriptions problem for an independent and identically distributed (i.i.d.) source, with feed-forward to one or both side-decoders is considered. A single-letter achievable rate-region is derived; it enlarges the best known rate-region for multiple descriptions without feed-forward.

Feeding rate and meal patterns in the laboratory rat

Physiology & Behavior, 1984
Many manipulations used in the study of feeding (e.g., changes of food taste or texture, anorectic drugs) affect the rate of food consumption. Consequent changes in meal patterning might reflect either direct effects of the manipulation or alternatively might result from indirect effects of the changed rate of intake.

Laboratory Observations on the Feeding Behavior and Feeding Rate of the Nemertean Procephalothrix simulus

The Biological Bulletin, 2008
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

Effect of Feeding Griseofulvin on Rate of Growth of Chicks

Nature, 1961
GRISEOFULVIN, 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 ...

Food, feeding rates and assimilation in woodland snails

Oecologia, 1970
Analyses 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, 1998
Abstract 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.

A Negative Feed-back Dosage-rate Meter

The British Journal of Radiology, 1948
A 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
