Visualization of toner ink adsorption at bubble surfaces

Flotation deinking involves interactions between inks particles and bubbles surfaces. These interactions are very difficult to observe directly or to quantify in bench-scale experiments or mill operations, making it difficult to evaluate effects of process conditions such as bubble size and solution chemistry on deinking efficiency. This paper presents images and measurements of toner ink interactions with bubble surfaces in laboratory-scale flotation processes. Stable adsorption of toner ink was observed at surfaces of stationary and suspended bubbles for several system chemistries. Interactions of toner particles and bubbles were quantified by high magnification and high temporal resolution digital videos obtained in bubble flow facilities creating both stationary and flowing bubbles. Large (>200 micron), flat toner particles adsorbed to bubble surfaces by single contact points. Smaller toner particles formed very stable complexes in fatty acid chemistries. Desorption of toner ink from bubble surfaces was not observed, even for vigorous flows. Bubbles were observed to be fully covered with toner after 4 minutes of residence time in the suspending bubble flow facility. Initial estimates indicate that bubbles with diameters of approximately 1 mm carry more than 1 mg of ink per bubble

Distributions of TOP, TON and TOC in the North Pacific subtropical gyre: Implications for nutrient supply in the surface ocean and remineralization in the upper thermocline

We report measurements of total organic phosphorus, nitrogen, and carbon (TOP, TON, and TOC) along a meridional transect in the eastern subtropical North Pacific. In the surface waters, TOP and TON comprise 83% and 98% of the total dissolved phosphorus and nitrogen pools, respectively. Between the equatorial region and the subtropical gyre, there is a distinct gradient in surface TOP of about 0.25 µM, but very little gradient in TON. TOC increases by nearly 30 µM across the same region. Meridional advection of TOP along its gradient via Ekman transport can provide 40-80% of the phosphorus necessary to supply present estimates of particulate phosphorus export from the subtropical gyre. Mass balance requires an additional input of nitrogen to the surface waters to fuel particulate nitrogen export. This input is likely supported by nitrogen fixation. As dissolved organic matter (DOM) is degraded along isopycnals that outcrop within the subtropical gyre, TOP and TOC are consumed more rapidly than TON. TOC and TON contribute 70% and 20% to organic matter remineralization along these isopycnals, respectively, and the C:N ratio for remineralization is 30 ± 10. In contrast, along isopycnals that outcrop to the north of the gyre, both TOC and TON contribute 30% to organic matter remineralization and the C:N ratio is 8 ± 1. Our results suggest that excess TOC, produced within the surface waters of the subtropical gyre during nitrogen fixation, is highly labile and dominates respiration along shallow isopycnals. Preferential remineralization of TOC relative to TON within the gyre results in a negative preformed nitrate signal in the upper thermocline, and may establish a feedback between upper thermocline DOM remineralization and surface ocean DOM production that maintains nitrogen fixation in the surface waters

British Balance of Competence Reviews, Part II: Again, a huge contradiction between the evidence and Eurosceptic populism. EPIN Paper No. 40, June 2014

This paper is the second in a series for a CEPS project entitled “The British Question and the Search for a Fresh European Narrative”. It is pegged on an ambitious exercise by the British government to review all the competences of the European Union on the basis of evidence submitted by independent stakeholders. In all, 32 sectoral policy reviews are being produced over the period 2013-2015, as input into public information and debate leading up to a referendum on whether the UK should remain in, or secede from, the EU, planned for 2017. This second set of reviews covers a broad range of EU policies (for the single market for goods, external trade, transport policy, environment, climate change, research, asylum, non-EU immigration, civil judicial cooperation, tourism, culture and sport). The findings confirm what emerged from the first set of reviews, namely that there is little or no case for repatriation of EU competences at the level they are defined in the treaties. This does not exclude that at a more detailed level there can be individual actions or laws that might be done better or not at all. However, that is the task of all the institutions to work at on a regular basis, and hardly a rationale for secession. For the UK in particular the EU has shown considerable flexibility in agreeing to special arrangements, such as in the case of the policies here reviewed of asylum, non-EU immigration and civil judicial cooperation. In other areas reviewed here, such as the single market for goods, external trade, transport, environment, climate change and research, there is a good fit between the EU’s policies and UK priorities, with the EU perceived by stakeholders as an ‘amplifier’ of British interests
