Popular Abstract in Swedish Jag har huvudsakligen studerat läderbaggen Osmoderma eremita, en ca tre cm lång skalbagge som lever inne ihåliga träd. Larverna av denna s k bladhorning lever av den döda veden på stammens insida i levande ihåliga lövträd (i Sverige främst ek) och av mulmen inne i trädet (den mjölliknande blandning av nedbruten ved, vedsvampar, löv, gamla fågelbon, fladdermöss, insekterThis thesis starts with a review of different biodiversity assessment methods in forests and the rest deals with the metapopulation ecology of Osmoderma eremita, a threatened beetle living in hollow trees. I concentrate on the effect of dispersal, habitat quality and habitat history for the presence, population size and future survival of this species. Dispersal was studied by using both capture-m

We introduce a common framework for the definition and operations on the different multiple view tensors. The novelty of the proposed formulation is to not fix any parameters of the camera matrices, but instead let a group act on them and look at the different orbits. In this setting the multiple view geometry can be viewed as a four-dimensional linear manifold in ℛ3m, where m denotes the

Small words like ‘yes’ and ‘no’ play an important part in our daily communication, but do we clearly know where they come from? Their origin is rather mysterious. We do not know if we need these words at all, since some languages manage without them. For instance, speakers of Celtic languages answer affirmatively and negatively by repeating verbs. However, functional motivations to have ‘yes’ and

Popular Abstract in Swedish Trots omfattande forskning är förståelsen för diffus hjärnpåverkan efter hjärtkirurgi och dess kliniska betydelse ofullständig. Avhandlingens syfte har varit att kartlägga kognitiv funktion efter kranskärlskirurgi och undersöka de kliniska konsekvenserna därav. Med neuropsykologiska test, intervjuer och frågeformulär har patienters subjektiva och objektiva kognitiva fuDespite considerable research efforts, the incidence and mechanisms of diffuse cognitive impairment after coronary artery bypass surgery are not fully understood. The aim of the dissertation was to describe cognitive changes after coronary artery bypass grafting (CABG) and the predictors and consequences thereof. Neuropsychological tests, interviews and questionnaires were used to assess objectiv

Popular Abstract in Swedish DNA är en molekyl som finns närvarande i stan alla celler och den innehåller den genetiska koden för utvecklingen av alla former av liv. Molekylen är väldigt tunn (2 nanometer i diameter) och lång - mänskligt DNA skulle vara ca en meter lång i utsträckt tillstånd. Inuti cellerna antar DNA en superkompakt struktur för att få plats inuti en cellkärna med bara ca 10 mikromThe structure, hydration, and dynamics of concentrated DNA-amphiphile complexes were investigated by small-angle X-ray diffraction, sorption calorimetry, and nuclear magnetic resonance. A concentrated, electroneutral, DNA-amphiphile complex can be formed by mixing charge-stoichiometric solutions. The effect is a strong association of DNA with the oppositely charged amphiphile resulting in the form

During the 1980s and the 1990s several researchers have described new organisational features and a new organisational form in multinational enterprises, linked to a variety of theoretical approaches. Can the new organisational features be analysed from a consistent theoretical basis, and can, hereby, a new organisational form be distinguished from earlier forms? The purpose of this dissertation i
