An improved method for the large-scale processing of woad (Isatis tinctoria) for possible commercial production of woad indigo
The increasing use of alternative crops has meant the introduction of new technologies to process their products. In this work, an alternative method is presented for the extraction of natural indigo from woad (Isatis ...
Reversal of parkinsonian symptoms in primates by antagonism of excitatory amino acid transmission: potential mechanisms of action.
Parkinsonism is characterised by overactive glutamatergic transmission in the cortico-striatal and subthalamo-medial pallidal pathways. Local blockade of glutamatergic transmission in these pathways can alleviate parkinsonian ...
Multivariable intelligent control strategies for an autonomous underwater vehicle
This paper discusses the application of a novel multivariable control technique to the problem of autonomous underwater vehicle (AUV) autopilot design. Based on an adaptive network structure a multivariable Sugeno style ...
Automated cold vapour flow-injection analysis of mercury at high concentrations.
Continuous-flow cold vapour- atomic fluorescence spectrometry is shown to be an extremely sensitive technique for the determination of mercury with detection limits typically below 0.01 mug l(-1). Linear calibration ranges ...
Self-similarity of the meddy family in the eastern North Atlantic
In this study we analyze two groups of Mediterranean salt lenses: "mid-life' lenses, typically 1-2 years old, observed in the Canary Basin, and younger Meddies from the Iberian Basin. Nonlinear transformation of variables ...
