Zeotropic mixture harmful effects that hydrochlorofluorocarbons (HCFC) and chlorofluorocarbons (CFC) have on the ozone layer and global warming. Researchers have focused on using new mixtures that have the same properties as past refrigerants to phase out harmful halogenated substances, in accordance to the Montreal Protocol and Kyoto Protocol. For example, researchers found that zeotropic mixture R-404A can replace R-12, a CFC, in household refrigerators. However, there are some technical difficulties for using zeotropic mixtures. This includes leakages, as well as the high temperature glide associated with substances of different boiling points, though the temperature glide can be matched to the temperature difference
1987 (What the Fuck Is Going On?) this West End musical shit do you? Come and do the new JAMMS [sic] album.'" In 1994, "The Guardian" looked back on the Swedish sojourn as "a grand, futile, attention-grabbing gesture, the kind that would come to characterise [the duo's] collaborative career...

The JAMs offered what they claimed were "the last five" copies of "1987" for sale at £1000 each in a full-page advertisement in the April 1988 edition of "The Face". Drummond argued that the offer exploited a loophole in The JAMs' agreement with the MCPS: "We were browsing
