Facility design measures included bedding type, bedding quantity, stall length and width, presence of a neck rail or brisket locator, and relevant distances from the rear and bed of the stall.
The inadequate length (too short) of the bed seems to be a more important factor in the development of body lesions than the bedding quantity, because we observed a higher frequency of body lesions in the cows in those farms with short beds and abundant bedding (4-5 kg/head/day) than in the farms with proper length beds and less bedding (1.5 kg/head/day or less).
The most affected body areas were the hock and the neck, probably because of the short beds, reduced quantity of bedding and the short chain used to tether the cows in some farms.
I met Prof Dan Parsons, of the University of Hull, on a boat carrying sonar equipment to measure the river bed and the quantity of sediment in the water.
Here, we illustrate this method using 420 500 μm glass ballotini and examine the behaviour of the bed for different quantities of fluidized material.
This experimental investigation deals with the observation of the behaviour that dense granular materials present when they flow in steady regime on a rough chute, focusing the attention on the transition to movement of the bed and on quantities involved as the internal friction angle.
Under the conditions of these tests, and for fixed mean rates G,L, the time averaged holdup and the pulse celerity are practically constant along the bed; furthermore, these quantities as well as the pressure drop do not seem to be affected by the imposed cyclic liquid feeding frequency.
His mother and I have always believed that the best treatment for a sick child is to be tucked up in bed, administered a minimal quantity of drugs, if any, and left to let the body's natural recuperative powers do their work.
Biologically effective dose (BED) is an approximate quantity to compare the different fractionation regimens.
