Electricity and potable water from a solar tower power plant
Rheinländer, Jürgen; Lippke, Frank - In: Renewable Energy 14 (1998) 1, pp. 23-28
The cogeneration of electricity and potable water utilising solar energy is studied, assuming solar tower power plants with the open volumetric PHOEBUS receiver. The results for alternative plant configurations show that the water production cost is about the same or even lower than the cost of...

A preliminary study on the feeding regime of European pilchard (Sardina pilchardus Walbaum 1792) in Izmir Bay, Turkey, Eastern Aegean Sea
Sever, T.M.; Bayhan, B.; Taskavak, E. - In: Naga 28 (2005) 3/4, pp. 41-48
The gut contents of Sardina pilchardus specimens captured in Izmir Bay were examined in order to determine their feeding regimes. Of the 365 stomachs examined, 321 (87.95%) contained food and 44 (12.05%) were empty. Analysis of gut contents verified that S. pilchardus feeds on zooplankton. The...
