1. 1. Searching for food in complex environments : Integrating processes at multiple spatial scales

   Författare :Thomas Alexander Verschut; Peter Hambäck; Peter Anderson; Ring Cardé; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Associational effects; Natal experiences; Olfaction; Oviposition; Plant Ecology; växtekologi;

   Sammanfattning : Resources are often unevenly distributed through the environment, resulting in a challenging task for insects to locate food, mates and oviposition sites. Consequently, there is an ongoing need to unravel how insects rely on behavioural and sensory traits while searching for resources in heterogeneous environments. LÄS MER

4. 3. Nuclear symmetry energy and neutron-proton pair correlations in microscopic mean field theory

   Författare :Shufang Ban; Ramon Wyss; Peter Ring; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : A major task of nuclear structure theory is to develop an effective interaction that is capable to predict properties of nuclei under extreme conditions. In this thesis three different areas of effective interactions have been studied: i) the density dependence, which is of importance for the understanding of neutron stars and neutron rich nuclei; ii) the symmetry energy which governs the evolution of the binding energy with changing N/Z ratio; and iii) the neutron proton pairing energy.

5. 4. Multiple Medicine Use : Patients’ and general practitioners’ perceptions and patterns of use in relation to age and other patient characteristics

   Författare :Janne Moen; Lena Ring; Karolina Antonov; J. Lars G. Nilsson; Peter Noyce; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Age groups; Focus group interaction analysis; General practitioners; Multiple medicine use; Patient-doctor communication; Patient-related factors; Polypharmacy; Community pharmacy services; Samhällsfarmaci; Social Pharmacy; samhällsfarmaci;

   Sammanfattning : There are widespread concerns about the increasing use of multiple medicines. The aims of this thesis were to identify older patients' and general practitioners' (GPs) attitudes to and experiences of multiple medicine use, as well as to describe patterns of multiple medicine use in different age groups in association with patient-related factors.
