The technique of replica casting of ceramic materials and the various methods of mounting and examination are described. Co-ordination of optical properties of the peels and X-ray analysis is considered. The uses of peels in showing orientation of clays settled under gravitation and also effects of plastic deformation are discussed.

Three trials were conducted with recently weaned pigs (n = 198) to determine the effects of feeding different types of clay in conjunction with aflatoxin-contaminated diets. In Trial 1, pigs (n = 54; trial length 4 wk) were assigned to either an uncontaminated treatment (NC), 800 ppb of aflatoxin from contaminated corn (AC), or AC with one of four clays. In Trial 2 (n = 81; trial length 5 wk), ...

small amounts of water to soil reduced the sorption of organic compounds relative to the sorption by the In soils, organic matter and minerals are often associated such that dehydrated soil in hexane, and that organic vapor adit is unclear how the presence of the former component influences sorption by soil was significantly depressed by increasing the sorptive properties of the latter one. In ...
