feed

The electrical element at the focus of a radio dish that collects the radio waves and feeds them to the receivers. The element may be a dipole connected to a transmission line, or a horn (called a feedhorn) connected to a waveguide. In both cases the physical size of the feed must be chosen to match the wavelength of the signal. A telescope capable of observing at a number of wavelengths may therefore possess a selection of feedhorns, any one of which may be moved to the focal point.

Feed

 

the relative motion of a cutting tool and workpiece on a machine tool; one of the main parameters that characterize the cutting mode during the working of articles on machine tools. Feed makes possible sequential extension of the cutting process to the entire surface being worked.

A distinction is made among continuous feed (for example, in lathes, drilling, and milling machines) and periodic feed (in planers and slotters) and between rectilinear feed (in lathes, drilling, and milling machines, and planers) and circular feed (during rotation of parts in certain grinding machines). Feed is measured in millimeters per revolution of the workpiece or tool (machine tools of the lathe group); in millimeters per double pass of the table or slide (planers); or in millimeters per minute, which is called time feed (milling machines).

In conclusion, grower olive flounder could achieve full compensatory growth up to 4-week feed deprivation when fish were fed with extruded pellet to apparent satiation once a day for 16 weeks or 15, 14, 13, 12 and 10 weeks after 1-, 2-, 3-, 4- and 6-week feed deprivation at suboptimal temperature.
Compensatory growth of the gibel carp following feed deprivation: temporal patterns in growth, nutrient deposition, feed intake and body composition.
Similarly, juvenile olive flounder fed the high protein and lipid diet (54.8% crude protein and 17.1 kJ/g energy) to satiation twice a day for 7 weeks after 1-week feed deprivation outgrew both the fish fed the control diet to satiation twice a day for 8 weeks (50.2% crude protein and 15.2 kJ/g energy) or 6 weeks after 2-week feed deprivation and the fish fed the high protein and lipid diet with supplementation of 5% amino acids after 2-week feed deprivation (Cho and Heo, 2011).
Results of this study indicated that supplementation of protein, carbohydrate, lipid and their combination into the diets could improve compensatory growth of olive flounder when fish were fed for 6 weeks after 2-week feed deprivation. The supplementation of dietary protein being the most effective of the supplements to improve compensatory growth of fish.
Results of this study demonstrated that juvenile olive flounder subjected to 2-week feed deprivation could achieve full compensatory growth in suboptimal temperature with dietary supplementation of protein or combined high protein and high lipid was more effective to improve compensatory growth of fish than dietary supplementation of lipid only.
Results of the present study revealed that feed deprivation up to 24 h after hatch had a transient detrimental effect on growth of broiler chickens, as they needed 21 days for compensation of initial loss in growth.
(2003) reported that the level of growth recovery that occurred after a period of feed deprivation depended on the physiological status of the animal.
Feed deprivation during molting is associated with increased plasma T4, H/L ratio, hematocrit and [Na.sup.+], while plasma T3 and [Cl.sup.-] are reduced.
