Clark (1969, 1973) and others (Lakoff Johnson, 1980 see also Tversky, this volume) maintain that this asymmetry of linguistic structure is rooted in the asymmetries of perceptual space. The clearest form of this argument was given by Clark, who pointed out that the structure of our bodies and our movements in the world define three reference planes, two of which are asymmetrical. The only plane characterized by perceptual symmetry is the right-left plane. Two reference planes are asymmetrical the front-back plane, and the top-bottom (or head-feet) plane. Clark claimed that the front end of the front-back plane is positive because it is the direction of movement and the side toward which most of our perceptual receptors are oriented. Similarly, he reasoned that the top end of the top-bottom plane is positive because up-down is the canonical orientation of the body as well as the primary direction of observed movement (objects fall from up to down but never in the opposite direction). The asymmetric structure of perceptual space has since been confirmed...

Calculate the flow (gpm) and head (feet of liquid) for each pump. Compare the observed head to the predicted head obtained from the pump curve at the corresponding flow. This is a measure of the loss in pump efficiency caused by wear to the impeller or wear rings (see Chapter 11). A tabulation of pump and heat-exchanger efficiency results for one performance test is shown in Table 27-3.

Viscera, gut contents, head, feet, skin, and bone are unpalatable but nutritionally rich by-products worth recycling, provided there is no risk of disease transmission. For example, a 100-kg live-weight pig yields a 75-kg carcass and 25 kg of offal and gut contents. The 75-kg carcass yields 57 kg of butcher meat, 4 kg of head, and 14 kg of skin and bones. The 57 kg of butcher meat is composed of 40 kg of lean meat and 17 kg of fatty tissue. Thus only 57% of a pig is edible butcher meat and 43% consists of slaughter by-products that have to be utilized as pet food or recycled into the food chain as protein supplements (see Fig. 8.3.1). If slaughter by-products are not recycled... 

A British term for a pork dish made from the chopped, cooked, and molded edible parts of pig s head, feet, legs, and sometimes tongue. Mock brawn differs in that other meat by-products are used.
