The Campanula genus comprises several economically important ornamental plants species. Wide hybridisation is a method to increase phenotypic variability, but is limited due to interspecies hybridisation barriers. In this study we investigated whether ovule culture could be used to increase the success rate of interspecific hybridisation between C.(More)
The aim of our work was to develop a step-wise concept for investigating neurogenic oropharyngeal dysphagia (NOD) that could be used by both trained nursing staff as well as swallowing therapists and physicians to identify patients with NOD at an early stage and so enable an appropriate therapy to be started. To achieve this objective, we assessed uniform(More)
The Montagu’s harrier (Circus pygargus) is a long-distance migratory raptor, breeding in Europe and Western Asia and wintering in sub-Saharan Africa. The population of the species has declined in Europe during the twentieth century, and Montagu’s harrier is red-listed in many European countries as declining or threatened. The main aims of the study were to(More)
Stiction is a major failure in microelectromechanical system (MEMS) devices in which two contacting surfaces can remain stuck together because of the adhesive forces. Due to the difference between the surfaces roughness and the adhesive force range, the real contact areas are usually smaller than the apparent one, resulting in a scatter in the adhesive(More)
