Prüfung neuer pilzwiderstandsfähiger Rotweinrebsorten auf ihre Anbaueignung in Franken

Five new fungus-tolerant grape varieties were tested from 2005 to 2010 in comparison to Merlot in Franconia/Germany. Crossings with Cabernet Sauvignon showed different ripening behavior, and aroma expression. Cabernet Carbon presented a full-bodied wine, whereas Cabernet Coral ranged sensorically near his cross parent Cabernet Sauvignon. Reberger as a very early ripening variety reached often plumy notes. All 5 varieties are not totally fungus resistant and need some plant protection depending on the yearly infection conditions. In specific years the tested Cabernet crossings had problems with stem dieback and bunch rot. Cabernet Carol and Cabernet Cortis reached the best results in relation to Merlot

Photovoltaic OLED Driver for Low-Power Stand-Alone Light-to-Light Systems

Photovoltaic (PV) stand-alone systems need to achieve multiple energy conversion modes. I.e. the energy conversion from PV to a local energy storage as well as energy conversion from the energy storage to the load. This paper documents the practical design considerations for the development of a three-port-converter for this purpose optimized for the specifications for driving an Organic Light Emitting Diode (OLED) panel intended for lighting purposes. By using a three-port-converter, featuring shared components for each conversion mode, the converter reaches 97 % efficiency at 1.8 W during conversion from photovoltaic panel to the battery, and 97 % in the area 1.4 W to 2 W for power delivery to the OLED
