Methods are provided for purifying peptides and proteins by incorporating the peptide or protein into a diketopiperazine or competitive complexing agent to facilitate removal one or more impurities, from the peptide or protein. The encapsulated file contains plural files and a deployment descriptor. The device for separating the caught pests from water and small debris has a shape of a funnel having a funnel inlet covered up by a mesh and an funnel outlet situated outside of the container for storing the caught pests. Four MTNCL architectures and four MTNCL threshold gate designs offer an asynchronous logic design methodology for glitch-free, ultra-low power, and faster circuits without area overhead. The element has a surface that is inclined at an oblique angle with respect to the planar surface. The present invention is suited for the characterization of commonly encountered microorganisms, as well as commercially and industrially important organisms from various and diverse environments.
