Rapid method for proline determination in grape juice and wine
No full textProline is typically the most abundant amino acid present in grape juice and wine. The amount present is influenced by viticultural and winemaking factors and can be of diagnostic importance. A method for rapid routine quantitation of proline would therefore be of benefit for wine researchers and the industry in general. Colorimetric determination utilizing isatin as a derivatizing agent has previously been applied to plant extracts, biological fluids, and protein hydrolysates. In the current study, this method has been successfully adapted to grape juice and wine and proved to be sensitive to milligram per liter amounts of proline. At sugar concentrations above 60 g/L, interference from the isatin-proline reaction was observed, such that proline concentrations were considerably underestimated in grape juice and dessert wine. However, the method was robust for the analysis of fermentation samples and table wines. Results were within ±10% agreement with data generated from typical HPLC-based analyses. The isatin method is therefore considered suitable for the routine analysis required to support research into the utilization or release of proline by yeast during fermentation.Danfeng Long, Kerry L.

A new nanocomposite as adsorbent and catalyst for enhanced removal of methylene blue
No full textIn this study, we present, for the first time, the preparation and characterization of a few-layer graphene (FLG)/ Fe3O4/Ag nanocomposite functionalized with polyacrylic acid (PAA) polymer for the removal of methylene blue (MB). X-ray Powder Diffraction (XRD) analysis confirmed the coexistence of Fe3O4 and Ag nanoparticles. The results demonstrate a high adsorption ability (qmax 141.60 mg/g) of the nanocomposites, achieving 98% removal of MB dye within 40 min at a concentration of 50 mg/L, with a nanoadsorbent amount of 100 mg. Furthermore, the findings indicate that the FLG/Fe3O4/Ag@PAA adsorbent maintains high dye removal efficiency over four consecutive cycles. The FLG/Fe3O4/Ag@PAA nanocomposites exhibit significantly enhanced catalytic reduction activity on organic pollutants. The reduction of MB can be completed in 300 s in the presence of NaBH4 as a reducing agent, using 5 mg of nanocatalyst and a concentration of MB dye of 50 mg/L. These results suggest that the nanocomposite can serve not only as an adsorbent but also as a promising catalyst for the reduction of organic dyes

The Dictator and the Parties A Study on Policy Co-operation in Mineral Economies
No full textThis paper develops a game to study the possibility of co-operative behaviour in a situation where the political system is dominated by two strong, opportunistic parties competing in an economy highly dependent on the export of a commodity. Since a binding agreement as an external solution is unlikely to succeed due to the close association between the incumbent party and the government (the guardian), the paper explores the extent to which co-operation between political parties that alternate in office can rely on self-enforcing strategies to provide an internal solution. For appropriate values of the probability of re-election and the discount factor, it is possible to rely on reciprocity to sustain an early-stopping equilibrium. However, cooperation is undermined by low values of re-election probability out of current revenues and party myopia. In those circumstances, the self-policing solution might not be viable and an institutional response would be necessary. The game also sheds some light on the apparent paradox of situations in some mineral- rich democracies (such as the recent Venezuelan experience) where the enjoyment of considerable external revenues is followed by a period of economic stagnation, a deterioration of political stability, and the surge of a dictatorship threat.Political Economy, Non-cooperative games, Democracy, Mineral Economies, Venezuela
