Investigating genetic factors behind the decline of a threatened plant species – Tephroseris integrifolia (Asteraceae)

Landscape change in Europe has caused the decline of many grassland species. Tephroseris integrifolia (Asteraceae) is one species which has declined rapidly in Sweden since the 19th century. A census of extant populations from 1980 to 2009 revealed a dramatic decrease in population sizes during the early 1990s, despite far-reaching conservation measures. Knowledge of causes of species decline is n

Internal Bremsstrahlung Accompanying the Positon Decay of 82Rb

The internal bremsstrahlung from the positon decay of 82Rb has been measured in the energy ranges 0.95-1.3 and 1.7-2.0 MeV. The measured intensity was about twice the value predicted by the charge-independent theory. The external bremsstrahlung produced in stopping the positons in Be, C and Al has been measured in the same energy intervals. Energies and intensities of the γ-rays from 82Rb have bee

Introductory Study of Variable Valve Actuation for Pneumatic Hybridization

Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. One solution to this is a pneumatic hybrid using variable valve timing to compress air during decele

The Arabidopsis 14-3-3 family -target protein specificity and expression of isoforms

14-3-3 proteins comprise a family of highly conserved proteins. 14-3-3 proteins have been found in all organisms examined except for members of the prokaryotic kingdom. 14-3-3s are involved in numerous processes in the cell and they typically bind to phosphorylated motifs in other proteins and regulate their activities. In plants, 14-3-3 proteins are recognized as key regulators of primary metabo

No Island is an "Island": Some Perspectives on Human Ecology and Development in Oceania

It has often been argued that the Earth is like an island in space and that its brittleness is most clearly reflected on small islands in the oceans. Easter Island, in particular, with its largely depleted resources, has been seen as a microcosmic warning about what could happen to our entire planet. However, the analogy of the Earth and islands with finite natural resources is not self-evident fr

New high resolution negative resist mr-L 6000.1 XP for electron beam and nanoimprint lithography

We present the characterization results of a new high resolution negative electron beam resist mr-L 6000.1 XP. The resist can also be used as imprintable polymer in nanoimprint lithography with sub-100 nm resolution. The feature size achieved after e-beam exposure was about 50 nm with sensitivity of 2-4 μC/cm2. Studies of the resist properties as a function of chemical composition and development
