Methods are provided for detecting biomolecular interactions. Thus, for example, the network interface can set the communication bandwidth, priority, or combination thereof, for each executing application based on the application type. The regeneration process can pass through an intermediate stage of forming an alkali carbonate by successive reactions with carbon dioxide and calcium oxide. In the solvent process, contaminated soils are run through a closed soil separator where the soils are washed with carbon dioxide. The invention is also directed to an oxidation oven having a plurality of cooperating drive rolls in series that can be driven independently of each other so that the amount of stretch applied to the oven in each of the plurality of passes can be independently controlled.
