A method and system for recovering a master boot record within a data processing system. A cam is connected to the post and has a guide slot which is cooperated with a piston rod of a cylinder. Qa, Qb, and Qc are a single bond or a divalent linking group. Versioned interfaces are placed between configuration components through data contracts. The flocculation is carried out by feeding the liquid manure in at a constant flow rate and introducing the reagent at the same time in the form of a tertiary or quaternary polymercopolymer, stirring the mixture for a time of between 5 and 15 minutes and then eliminating the suspended solids by flotation, involving the coalescence of the colloidal particles.
