These constant swimming speeds between the surface and depth-of-feeding suggests they are optimum speeds and that they are likely a function of physical laws.
By gradually increasing the depth of the feeding tray the ducks were trained to perform feeding dives to 1.5 m.
We also chose forbs whose roots commonly grow to the depth of gopher feeding tunnels (∼10 20 cm [54], [55]).
The villus height in duodenum, ileum and jejunum, and the ratio of villus height to crypt depth of piglets fed with L. plantarum/pPG-pLF showed significantly increased levels.
Tagged whales varied the depths of their feeding dives to: i) track diurnal changes in the vertical distribution of krill; ii) match changes in prey density at depth; and/or iii) forage along edges of the prey aggregation (Figure 2).
The optimal values of these parameters were 8D of feeding zone length, 15 mm of feeding zone depth, 4D of melting zone length, 3 of compression ratio, 49 rpm of screw speed, and 165/180/200/250/260/2660/260 of barrel temperature.
The machining parameters under investigation were depth-of-cut, feed rate, surface cutting speed, tool radius, tool rake angle and side rake angle, and cutting fluid.
The surface roughness model is developed in terms of cutting speed, rate of feeds and depth of cut.
The input parameters were the radial depth of cut, feed rate, and contact angle.
Using the design of experiments method, full factorial technique, 33×2 tests were conducted to study the influence of effective parameters i.e., magnetic field, depth of cut, feed rate and spindle speed.
The factors considered for DOE in the experiment were the depth of cut, feed rate per tooth, cutting speed, tool nose radius, the use of cutting fluid and the three components of the cutting force.
