Carbon acquisition in relation to CO 2 supply was investigated in three marine bloom-forming microalgae, the diatom Skeletonema costatum, the flagellate Phaeocystis globosa, and the coccolithophorid Emiliania huxleyi. In vivo activities of extracellular (eCA) and intracellular (iCA) carbonic anhydrase activity, photosynthetic O 2 evolution , CO 2 and HCO(More)
Rates of cellular uptake of CO 2 and HCO 3 Ϫ during steady-state photosynthesis were measured in the marine diatoms Thalassiosira weissflogii and Phaeodactylum tricornutum, acclimated to CO 2 partial pressures of 36, 180, 360, and 1,800 ppmv. In addition, in vivo activity of extracellular (eCA) and intracellular (iCA) carbonic anhydrase was determined in(More)
An Intelligent Inspection Engine (IIE) for classiication of non-regular shaped objects from images is described and evaluated using real-world data from a waste package sorting application. The entire system is self-organizing. Principal component analysis and additional a priori knowledge on color properties are used for feature extraction. As classiiers(More)
The effect of variable concentrations of dissolved molecular carbon dioxide, [CO 2,aq ], on C : N : P ratios in marine phytoplankton was studied in batch cultures under high light, nutrient-replete conditions at different irradiance cycles. The elemental composition in six out of seven species tested was affected by variation in [CO 2,aq ]. Among these(More)
1. ABSTRACT Localising the current distribution in the human brain from extracranial EEG/MEG-measurements is an Inverse Problem whose solution requires the repeated simulation of the electric/magnetic propagation for a given dipolar source in the brain using a volume-conduction head model. The simulations are referred to as the Forward Problem. In order to(More)
