Hydrogen can be recovered by fermentation of organic material rich in carbohydrates, but much of the organic matter remains in the form of acetate and butyrate. An alternative to methane production from this organic matter is the direct generation of electricity in a microbial fuel cell (MFC). Electricity generation using a single-chambered MFC was examined using acetate or butyrate. Power gene...

We have designed a novel working strategy to optimize a unique chromatographic method consisting of diode array detection for the analysis of the most representative phenolic compounds from different food sources. The simultaneous inclusion of standard phenolic compounds, phenolic compounds isolated from food sources and representative real extracts as an ultimate test in analysis has allowed t...

conclusions the sex differences in the neuroanatomy of the human mirror neuron system affect functional recovery of patients with hemiparesis. the improvement in studied women was found to be significantly greater than studied men. the results indicate a higher chance of recovery among hemiparetic women, especially those watching functional movies. results comparison of all variables related to...

Conventional techniques for project planning make the flawed assumption that all activities and relations are known and can be planned a priori. Iteration models show that iteration is a fundamental aspect of novel projects, but they also assume all activities and interactions are known. Of course, some kind of hypothesized project baseline (plan) is required for management. Such plans are ackn...

A number of approaches for evaluating recovery and its contribution to uncertainty budgets for analytical methods are considered in detail. The recovery, R, for a particular sample is considered as comprising three elements, R̄m, Rs and Rrep. These relate to the recovery for the method; the effect of sample matrix and/or analyte concentration on recovery; and how well the behaviour of spiked sam...
