Background: Environmental challenges may affect both the exposed individuals and their offspring. We investigated possible adaptive aspects of such cross-generation transmissions, and hypothesized that chronic unpredictable food access would cause chickens to show a more conservative feeding strategy and to be more dominant, and that these adaptations would be transmitted to the offspring. Methodo
Long-term selection (>45 generations) for low or high body weight from the same founder population has generated two extremely divergent lines of chickens, the low (LWS) and high weight (HWS) lines, which at the age of selection (56days) differs by more than nine-fold in body weight. The HWS line chickens are compulsive feeders, whereas, in the LWS line, some individuals are anorexic and others ha
The possibility to engineer nanowire heterostructures with large bandgap variations is particularly interesting for technologically important broadband photodetector applications. Here we report on a combined study of design, fabrication, and optoelectronic properties of infrared photodetectors comprising four million n+–i–n+ InP nanowires periodically ordered in arrays. The nanowires were grown b
Core–shell nanowires offer great potential to enhance the efficiency of light-emitting diodes (LEDs) and expand the attainable wavelength range of LEDs over the whole visible spectrum. Additionally, nanowire (NW) LEDs can offer both improved light extraction and emission enhancement if the diameter of the wires is not larger than half the emission wavelength (λ/2). However, AlGaInP nanowire LEDs h
Although they are often subjected to critical scrutiny, formal geopolitical practices have rarely been put on trial. One exception is the case of Gudmund Hatt (1884-1960), professor of human geography at Copenhagen University from 1929 to 1947, who was found guilty of “dishonorable national conduct” for his geopolitics during the German occupation. As a contribution to the critical history of geop
Over the past decades, a ‘neoclassical geopolitics’ has emerged in and beyond the field of International Relations. This diverse practice reproduces many of the problems that characterised classical geopolitics, notably an excessive tendency to explain politics on the basis of ostensibly permanent geographical factors. As a contribution to the interdisciplinary dialogue between International Relat
