Abstract: Methods of treating animal organic material are disclosed herein. The methods include diluting the animal organic material to produce an organic material slurry, anaerobically digesting the organic material slurry to produce a biogas and a digestate, separating the digestate to produce a digestate solids and a filtrate, removing ammonia from the filtrate, removing organic contaminants and divalent anions from the filtrate, concentrating the filtrate to produce a retentate and a permeate, combining the digestate solids and the retentate to produce a solids product, and returning the permeate to dilute the animal organic material. Systems for treatment of animal organic material are also disclosed herein. The systems include a dilution tank, an anaerobic digester, a first solids-liquid separation subsystem, an ammonia-reducing column, a second solids-liquid separation subsystem, a production water storage tank, and a solids product tank.

Abstract: A computer system development tool for managing interoperability between client applications and server applications in differing APIs. The tool includes source code sample files having an index section, a conditional statement section, and a subroutine section. Each source code sample files is defined in a language conforming to one of the APIs. The subroutines in a source code sample file define by example the interoperability of the source code sample API with other APIs. The source code sample file conditional statement section sets out the varying interoperability constraints and the index permits a developer to locate sections of the source code sample file of interest for a given interoperability issue.

Abstract: A pair of clamps for mounting a level to a joist. Each clamp includes a pair of spaced apart spring biased arms having first ends for gripping the joist. A mounting hole at the lower end of each clamp receives the opposite end of a level which is releasably secured therein. The method of measuring the level of a member includes the steps of mounting the clamps and level to the joist to be measured.
