No full textEffect of rare earth elements on growth and antioxidant metabolism in Lemna minor L
No full textLemna minor is frequently used in bioremediation processes to remove nutrients and contaminants from
waste water. In this work the response of L. minor to treatments with lanthanum nitrate and with a mix of several
light rare earth elements (REE) nitrates was investigated. Preliminary results indicate that L. minor shows an overall
good tolerance to the presence of REE in the media. Toxic effects were observed after prolonged exposition to high
concentration of REE. An increase in ascorbate and glutathione content as well as in ascorbate peroxidase, dehydroascorbate
reductase and ascorbate free radical (AFR) reductase activity was observed in treated plant

Application of the IS-MP-IA model to the German economy and policy implications
No full textExtending the IS-MP-IA model developed by Romer (2000) and applying the GARCH (Engle, 1982, 2001) methodology, the author finds that equilibrium GDP in Germany is positively affected by stock market performance and real exchange rate appreciation, and negatively influenced by the expected inflation rate, the government deficit/GDP ratio, and the U.S. federal funds rate. The relatively low deficit/GDP ratio of 1.83% in 2003 indicates that its fiscal condition was healthy. However, some other EU members may need to exercise fiscal discipline. Because real appreciation has a positive impact on output, a stronger euro may not be a concern for Germany but may be worried by those EU member nations which depend upon exports to stimulate their economies.
