Wirtschaftlichkeit von Bioethanol – Produktion und Produktionskosten im nationalen und internationalen Vergleich

In this article the profitability of the bioethanol production in Germany is analysed under consideration of the international competition. Therefore, the production costs of bioethanol from wheat and beet in Germany as well as from sugar cane and corn in other representative countries are compared. Based on this, the competitiveness of imported as well as domestic bioethanol against gasoline on the German market are analyzed and the maximum payable feedstock price for sugar beet is calculated. The calculations lead to the result, that, despite the implemented mandatory blending, further cost reductions for the production of bioethanol in Germany are required in order to achieve competitiveness against imports, whereas the utilization of bioethanol is independent of the crude oil price within the targets of the mandatory blending scheme.bioethanol, competitiveness, sugar beet, Resource /Energy Economics and Policy,

18F-FDG-PET Detects Drastic Changes in Brain Metabolism in the Tg4–42 Model of Alzheimer’s Disease

The evaluation of new therapeutic strategies in Alzheimer’s disease (AD) relies heavily on in vivo imaging and suitable animal models that mimic the pathological changes seen in patients. 18F-Fluorodeoxyglucose (18F-FDG)-positron-emission tomography (PET) is a well-established non-invasive imaging tool for monitoring changes in cerebral brain glucose metabolism in vivo. 18F-FDG-PET is used as a functional biomarker for AD as patients show an early and progressive reduction of cerebral glucose metabolism. However, earlier studies in preclinical models of AD showed conflicting results. The aim of this study was the evaluation of cerebral glucose metabolism in the Tg4–42 mouse model of AD using 18F-FDG-PET/magnetic resonance imaging (MRI). Tg4–42 mice show an age-dependent reduction in glucose metabolism together with severe neuron loss and memory deficits. Similar to AD patients early decrease in 18F-FDG uptake was already detected in young (3 months) Tg4–42 mice. The altered glucose metabolism coupled with age- and disease related cognitive decline of Tg4–42 mice make it a well-suited model for preclinical testing of AD-relevant therapeutics

Konkurencyjność brazylijskiego bioetanolu w Unii Europejskiej

The new EU legislation on biofuels, which allows a full exemption of petrol tax in the member states, has led to a positive investment climate particularly in Germany. At the same time, the fact that bioethanol can be produced at much lower costs in other parts of the world than in Europe should not be ignored. This article, therefore, aims to analyse the production costs of bioethanol in Brazil, the world's largest producer and exporter.Nowe ustawodawstwo dotyczące biopaliw, które pozwala na zwolnienie z podatku od paliw w krajach członkowskich Unii Europejskiej, prowadzi do powstania sprzyjającego inwestycjom klimatu w Niemczech. Jednocześnie nie można ignorować faktu, że w innych regionach świata koszty produkcji biopaliw są niższe, stąd celem niniejszego artykułu jest analiza kosztów produkcji bioetanolu w Brazylii, kraju, który jest największym światowym producentem i eksporterem tego paliwa
