21. On the Design of Energy Efficient Aero Engines: Some Recent Innovations
Abstract : In the light of the energy crisis of the 1970s, the old aerospace paradigm of flying higher and faster shifted towards the development of more energy efficient air transport solutions. Today, the aeronautical research and development community is more prone to search for innovative solutions, in particular since the improvement rate of change is decelerating somewhat in terms of energy efficiency, which still is far from any physical limits of aero engine and aircraft design.

23. Deterioration of recent oak by iron compound : a comparison with Vasa oak
Abstract : Wood degradation in the historical warship Vasa has been studied systematically regarding the chemical and physical properties. The presence of iron(II) seems to be one important factor for the degradation of the wood, causing reduction of its tensile strength. This is unfortunately a serious problem as iron(II) compounds are abundant in Vasa wood. READ MORE

25. Sandgrunnorna in Lule Archipelago : Recent Transformation of a Glaciofluvial Deposit in an Environment of Land Uplift
Abstract : In an area of rapid land uplift the geomorphological evolution of the glaciofluvial island of Sandgrunnorna, 25 km SE Luleå, in the Bothnian Bay, is discussed from old maps, air photographs and field studies. The island were marked on a map for the first time in 1790, but the highest parts can be estimated to have reached the sea surface about 100 years earlier. READ MORE
