This invention relates uses of Toxoplasma gondii chorismate synthase, a component components of plant-like metabolic pathways not including psbA or PPi phosphofructokinase and not generally operative in animals or encoded by the plastid DNA, in assays to develop compositions that interfere with Apicomplexan growth and survival. The device is plugged into an electrical outlet using a set of prongs like those used in the electrical plugs of typical household appliances. One disclosed system alters the manner in which a file delete command is implemented, depending upon whether the file is stored in a write-once memory or in a re-writable memory. Next, the event processing engine identifies related events associated with each of the identified entities. It is submitted with the understanding that is will not be used to interpret or limit the scope or meaning of the claims. The pants thus constructed can be smoothly pulled up to a desired level at which the pants are properly worn.
