A method for manufacturing polymer fine particles having a narrow particle diameter distribution without any particular limitations on the raw materials and the like. To achieve this purpose, this method for manufacturing polymer fine particles includes polymerizing a vinyl monomer using a dispersion polymerization method, wherein the amount of water in the reaction liquid in the polymerizing is no more than 30,000 ppm, the reactor for carrying out the polymerizing is a stirring tank reactor, the stirring blade attached to the stirring rotation shaft of the stirring tank reactor is one type selected from a large wide blade and a large lattice blade, and the tip speed of the stirring blade is no more than 1.0 m/sec.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.

The invention provides a method for producing prion protein having an aggregated conformation by contacting native conformation prion protein with aggregated conformation prion protein in a liquid preparation and subjecting this to at least one cycle or to a number of cycles of application of shear-force for fragmenting aggregates of prion protein, wherein the shear-force applied is precisely controlled. In addition to this process for amplification of aggregated state prion protein from native conformation prion protein, the invention relates to the aggregated state prion protein obtained by the amplification process, which aggregated state prion protein has one conformation, which is e.g. identical within one batch and reproducible between batches, e.g. as detectable by proteinase resistance in a Western blot.
