Many passerines migrate during the night and at high altitudes, making their migration difficult to observe. By using tracking radars we have been able to make exact observations of the flight behaviour of passerines on nocturnal migration, which has enabled us to test several hypotheses about adaptive values and constraints regarding migratory behaviour in different ecological contexts. We have i
The starting point for this dissertation can be characterised with the question: why don't dreams come true? In 1900, Ellen Key proclaimed the coming hundred years as the children's century. One of the great questions of the time concerned the relation between the individual and the community. Through the years, school curricula became influenced by visions of "reform-pedagogics" (Reformpedagogik)
Background: As older gastric cancer patients are often excluded from randomized clinical trials, the most appropriate treatment strategy for these patients remains unclear. The current study aimed to gain more insight in treatment strategies and relative survival of older patients with resectable gastric cancer across Europe. Methods: Population-based cohorts from Belgium, Denmark, The Netherlands
BACKGROUND:: Pneumococcal conjugate vaccine (PCV) was introduced in 2000. The first 7-valent vaccine was followed by a 13-valent vaccine (PCV13) with the same conjugate, and a 10-valent vaccine (PCV10), conjugated to protein D from H. influenzae. The vaccines offer some protection against pneumococcal acute otitis media (AOM), and, with PCV10, possibly also some protection against H. influenzae AO

Background: We here study antibodies against phosphorylcholine (anti-PC) which we reported to be inversely associated with atherosclerosis, cardiovascular disease (CVD), and autoimmune conditions. In previous studies, we determined that this inverse association is more pronounced at low levels with high risk and at high levels, with decreased risk. We compare individuals from Kitava, New Guinea (w
Driven by increased expectations on the use of knowledge to benefit sustainable social development and growth, the government’s research and innovation bill in 2012 highlighted the need to develop new incentives and structures to foster universities’ interaction with surrounding society. Following this, the government assigned Vinnova the task of developing methods and criteria for assessing the p
