Motion is a powerful cue for figure-ground segregation, allowing the recognition of shapes even if the luminance and texture characteristics of the stimulus and background are matched. In order to investigate the neural processes underlying early stages of the cue-invariant processing of form, we compared the responses of neurons in the striate cortex (V1)(More)
The simultaneous analysis of 14 diuretics in human urine (belonging to five different pharmacological groups) by reversed-phase high-performance liquid chromatography (HPLC) with a diode-array detector was developed by using a gradient elution with acetonitrile and phosphate buffer containing propylamine hydrochloride on a Bondclone-ODS (10 microns) column.(More)

The cultivatioo of narrow·leafed lupins (Lupinus angustifolius L) increases rates of subsoil acidification, and this is thought to be partly related to their pattern of nutrient uptake and H+ jOHexcretion. The main hypothesis of this study was that H+ and OHexcretion is not distributed evenly over the entire length of the root system but is limited to zones(More)
