Two studies concerning low molecular weight organic acids in soils were conducted. In the first study, anion exclusion chromatography was used to separate and identify 12 common organic acids, and the accuracy, precision and detection limits of the method were determined. The method was found to be sensitive and accurate...
A novel technology for processing pulp slurries with high inorganic filler content and at high consistencies (solids content) is extrusion. The paper industry waste comprises of fibers mixed with inorganic filler content. Using extruders similar to food extruders and consistencies ranging from 30-45%, profiles can be extruded from this waste...
Decision support systems (DSS) have been used to a very limited extent in pond aquaculture. This study documents the development of a DSS (POND) which allows representation of an entire pond aquaculture facility, and provides analysis capabilities in the form of simulation models and an economics package. Simulation tools in...
