Abstract: A pendant for a necklace has a body with an aperture, and a hole extending into the body from the aperture. The hole terminates at a closed bottom in the body. A body coupling is adjacent the aperture. A lid can be attached to and detached from the body. The lid also can be mounted to the necklace to support the body therefrom. The lid has a lid coupling to couple to the body coupling to close the aperture. The lid coupling can be uncoupled from the body coupling to provide access to the hole. A container is removably mounted in the body. The container has a retained position where the container is in the hole in the body when the lid is mounted to the body. The container also has a released position with the lid detached such that the container is at least partially exposed from the body.

Abstract: A system and method for determining the effectiveness of an anaerobic digestion process. The system includes a particle imaging system capable of capturing images of particles, including anaerobic microorganisms, in a fluid and counting those images. The method includes use of the captured image information to relate acquired microorganism information to anaerobic digestion process conditions. The information is further used in the method to adjust the digestion process as may be needed. This allows for an inexpensive means of confirming the bio-assay of an anaerobic sludge and the results of various performance strategies of anaerobic digestion, and may be correlated to a reliable methane output. After verification of the assay genetically, and images correlated to their genetic material, various biological experiments can be performed with exponential reductions in program and laboratory expenditures.
