The Impact of the European Union Emissions Trading Scheme on the Polish Economy:Interviews with Four Companies in Poland

This paper reports the results of interviews with four Polish companies. The results of the interviews shows that Polish companies tend to evaluate the effects of the introduction of EU ETS in 2005 positively: it provided an alternative view that they need considering environment in their business, and that they had much useful information for the improvement of energy losses by measuring it to verify the amount of emissions. However, there are also several negative claims to the EU ETS: auction adopted in the EU ETS from 2013 not only requires purchasing allowances, but also increases production cost due to the rise in the electricity price. Moreover, some of them are concerned that the competitiveness of Poland might be weakened, since it deeply depends on coal.

Sex-inducing effects toward planarians widely present among parasitic flatworms

Summary Various parasitic flatworms infect vertebrates for sexual reproduction, often causing devastating diseases in their hosts. Consequently, flatworms are of great socioeconomic and biomedical importance. Although the cessation of parasitic flatworm sexual reproduction is a major target of anti-parasitic drug design, little is known regarding bioactive compounds controlling flatworm sexual maturation. Using the planarian Dugesia ryukyuensis, we observed that sex-inducing substances found in planarians are also widespread in parasitic flatworms, such as monogeneans and flukes (but not in tapeworms). Reverse-phase HPLC analysis revealed the sex-inducing substance(s) eluting around the tryptophan retention time in the fluke Calicophoron calicophorum, consistent with previous studies on the planarian Bipalium nobile, suggesting that the substance(s) is likely conserved among flatworms. Moreover, six of the 18 ovary-inducing substances identified via transcriptome and metabolome analyses are involved in purine metabolism. Our findings provide a basis for understanding and modifying the life cycles of various parasitic flatworms.journal articl
