The use of microalgae as feedstocks for biodiesel is potentially limited by climatic conditions with low light and temperature levels. Monoraphidium sp. Dek19 was identified by 18S rRNA gene sequencing. This is a species indigenous to the upper Midwestern USA which grows to high densities in wastewater with bioremediation resulting in a reduction of nitrate and phosphate levels. Mesocosm pool cultures (171L) were used to characterize growth of this species in larger volumes than typical of previous lab-based studies,. The alga was shown to be cold-tolerant and to grow to workable density within 15 days at relatively low light intensities in sterilized treated effluent. It was harvested by FeCl3 flocculation and filtration, and lipid content was measured at 26% of dry weight. Pool cultures yielded enough biomass to extract lipids and transesterify them to biodiesel for testing in a stationary engine. GC analysis showed FAMEs produced from Monoraphidium sp. to have a similar fatty acid profile to soybean oil. Engine testing of this algal biodiesel in blends with petrodiesel showed

This case describes the development of a unique, student-centered, online course management systems (OCMS). The system grew from a fairly straightforward grade reporting system into a full-blown collaborative system within a short — in traditional information systems development terms — timeframe of approximately one year. The Community/course Action/interaction Management System, known as CAMS©, was developed iteratively with specifications derived from faculty and students working together to address the limitations of existing OCMS and to identify new functions and features that would contribute to the value of the educational experience. To address the most critical issue identified — limited interactive functionality — the participant became the focus of the development process. This case describes the evolution of CAMS© from both a product and a process perspective. Changes made to the system and the factors motivating the changes are discussed, as are challenges faced before, during, and after the development process.
