The critical process parameter for mineral separation is the degree of mineral liberation achieved by comminution. The degree of liberation provides an upper limit of efficiency for any physical separation process. The standard approach to measuring

Four species of non-native coccinellids in North America have expanded their ranges to include Cape Breton Island, Nova Scotia in the past 20 years. Lady beetles were sampled in 1998 at five sites in industrial Cape Breton to determine the status of

Porous cup samplers are the most frequently used devices to collect water samples from unsaturated porous materials. The time-averaged rate at which a sample is collected (Rs) varies considerably depending on the porous cup material and among sampler

Laboratory experiments were conducted to examine the radius of soil (sand) sampled (Sr) by a porous cup sampler. Sr was defined by the detection of potassium bromide (KBr) in a sample when KBr was injected at horizontal distances of 5, 10, 15, 30, an

Laboratory investigations were conducted to measure seasonal longevity and the effect of nut maturity on the puncturing of nuts and oviposition activities of Curculio caryae (Horn). Females lived longer than males, and pecan weevils that emerged earl

The dispersal of Menochilus sexmaculatus (F,), an imported aphidophagous lady beetle from Pakistan, was studied by releasing 848 beetles in 1975 and 2050 beetles in sorghum fields in 1976. Eight hours after release, 28% of the beetles remained within
