A review of patents and literature reveals an evolution in materials technologies. The evolution has been driven by an increased understanding of the physiological needs of the cornea, beginning with the first hydrogel lenses developed by Wichterle, followed by a variety of high water hydrogels. Oxygen transmission requirements have been addressed through(More)
Chestnut (Castanea sativa Mill.) coppice is a man-made forest type that has been managed for centuries in short rotations to rapidly produce woody biomass. These forests, which nowadays cover significant areas within Europe, experience a general neglect and are subsequently being abandoned. Most of them are now over-aged, very dense, and highly monotone.(More)
Morphological plasticity helps plants to cope to environmental conditions. Allometric responses of the mangrove Avicennia germinans to increasing salinity are easily detectable when focusing on the top height trees. Several studies show that mangrove trees possess high species- and site-related trait allometry, suggesting large morphological plasticity that(More)

Stable isotope tracers do not have approval for diagnostic use in humans. We assume that stable isotope tracers behave like natural compounds, because there is no evidence for the opposite despite a wide use in human studies. From this point of view, they are drugs comparable to unlabelled natural substances. Under this assumption a pharmacy is allowed to(More)
