Use of earthworm species to biodegrade various substrates (industrial wastes, agricultural residues, etc.) for composting has proven to be successful after initial stabilization of vermi beds. This study presents optimization of vermi beds (soil + cowdung) for culturing of earthworms (Eisenia fetida, Eudrilus eugeniae, and Megascolex megascolex.). Optimum proportion of soil + cowdung (1:3) for ...

Steingrimsson and Luce (2003a) outlined the second author’s proposed psychophysical theory (Luce, 2002, 2003a,b) and tested behavioral attributes that, separately, gave rise to one psychophysical function, Ψ, that maps pairs of physical intensities onto the positive real numbers that represents subjective summation and a second one, Ψ∗,that represents a form of ratio production. This article ta...

We studied how soil pH (pHs 4 to 8) influenced the mineralization of low-molecular-weight (LMW)-dissolved organic carbon (DOC) compounds, and how this compared with differences in microbial community structure. The mineralization of LMW-DOC compounds was not systematically connected to differences in soil pH, consistent with soil respiration. In contrast, the microbial community compositions di...

The paper addresses control related design issues for neutralization plants. Mainly for control reasons, the neutralization is usually performed in several steps (mixing tanks) with gradual change in the concentration. The aim is to give recommendations for issues like tank sizes and number of tanks. Assuming strong acids and bases, we derive linearized relationships from the disturbance variab...
